A Forward Compatible IoT Protocol and Framework Addressing Concerns due to Internet-outage
by Gourinath Banda, Krishna Chaitanya Bommakanti, Harsh Mohan, Abhay Chandra
Abstract: Internet of Things (IoT) paradigm is becoming ubiquitous in everyday life. IoT-based systems are increasingly getting deployed in generic household,health-care, public utilities, etc. related application. The reason for such rapid acceptance is in majority due to the Internets feature of connect from anywhere. However, due to some weaknesses inherent with the internet itself,IoT deployments also face certain challenges. Though there is a growing number of IoT-related reference architectures, frameworks, guidelines, platforms and standards, majority of them are yet to address the concerns due to internet outage. Furthermore, such growing numbers of architectures, frameworks, etc. also means bountiful amounts of both opportunities and risks for IoT vendors and original equipment manufacturers (OEMs). Of course, the IoT-device consumers also run the risks if the purchased products frameworks incompatible. We present OneIoT version2 (v2), an IoT framework and protocol that addresses the internet outage scenario. Similar to version1 (v1), One IoT v2 is also forward compatible.

Trust Assessment of X.509 Certificate Based on Certificate Authority Trustworthiness and its Certificate Policy
by Zakia El Uahhabi, Hanan El Bakkali
Abstract: Nowadays, X.509 certificate is largely used to prove its holder identity in open networks. Then, the Relying Party (RP) needs an automated mechanism for evaluating its trustworthiness in order to decide whether to accept it or not. In this context, we provide him with this mechanism allowing him to decide if he should trust in a received certificate or not. In our previous work, we have proposed an architecture for calculating a certificate trust level. Using a defined algorithm, this level is computed depending on three parameters: the calculated trust level of certificate authority (CA), the certificate policy quality, and the rating of the certificate fields. In this paper, we improve the algorithm used to calculate a CA trust level on the basis of trust level of the CAs that had issued certificates for it and their extension fields. By this way, the calculated trust level reflects a real trustworthiness of certificate because it is computed on the basis of the real factors inﬂuencing this trustworthiness. It is then more relevant for a relying party when deciding whether to accept a received certificate or not.

by Ali Al Farawn, Nabeel Salih Ali, Munqath Alattar
Abstract: Recently, providing services remotely over a network to enhance functionality and usability has become a trend. Such services are banking management systems, social applications, and online marketing. These applications regularly contain sensitive and personal information that should be managed and controlled by
authorized persons and as the policies they actually have. This concept results in one of the main concerns and a big challenge for the online services, i.e., privacy. The commonly used method to retain the privacy is by assigning authentication information for each user. Such information is a public username and private password. Thus, keeping the password security is important to
prevent unauthorized users from impersonating other legal users. Hashing the password is one of the safety methods and means of preventing attacks. In this study, we proposed an iterative salted hash encryption mechanism named Anti-Continuous Collision Salted Hash Encryption (ACCSHE) that uses Cryptographically
Secure Pseudo Random Number Generator (CSPRNG) and hashed with password data by Secured Hashing Algorithm (SHA-256). The outcome manifests a flexibility of changing the results by controlling several key features, such as salt used, the range of the hashing process iterations or the minimum number of iterations
without affecting the systems usability. The system efficiently prevented continues collision issue and effective processing time cost for an attacker.

by I. Sumaiya Thaseen, Ch. Aswani Kumar
Abstract: Purpose - A lot of intrusion and hacking events are surrounding the internet domain, bringing in a need for security systems. Intrusion Detection System (IDS) safeguards the network from any attack by continuous monitoring of the system activities. The major issue for any intrusion detection model is to identify anomalies with maximum accuracy and minimal false alarms.
Design/Methodology/Approach - An intrusion detection model is developed combining chi-square feature selection and LPBoost algorithm. Chi-square feature selection is deployed to build the optimal features as the network traffic data consists of many attributes. The optimum features are utilized by the LPBoost algorithm for recognizing the regular traffic and diverse attacks in the network. An ensemble classifier is chosen as they typically outperform a single classifier.
Findings - The investigational analysis is performed using NSL-KDD and UNSW-NB data sets. The experiments clearly show that the hybrid model achieves a higher detection and reduced false positive rate in contrast to other techniques.
Originality/Value- The key contribution of the model is the feature extraction and optimization of the ensemble parameter for improved accuracy of the model. Feature extraction minimizes the computation time and only essential features required for classification are retained in the sample set. The optimization of trade-off parameter in the ensemble ensures the desirable cross-validation accuracy is achieved. The model is tested on recent attacks present in the UNSW-NB dataset.

by Hayet Benkerrou, Mawloud Omar, Fatah Bouchebbah, Younes Ait-Mouhoub
Abstract: Trust and reputation evaluation in the Internet of Things (IoT) constitutes nowadays a major challenge that is still attracting the research community to work on and investigate. The IoT with its widely heterogeneous objects requires collaborative computation to perform heavy cryptographic operations in the most constrained resource devices. Indeed, the effectiveness of the trust and reputation assessment plays an important role for selecting the best collaborators. In this paper, we propose a dependable and lightweight trust proliferation approach for the collaborative IoT systems. By recording the malicious tasks which could be performed during the service execution, our approach introduces a new derivation of direct trust. Furthermore, it combines dynamically the direct and indirect trust evaluation to ensure more trustworthiness and reliability in the selection of the best collaborator objects. Through the simulations, we show that our trust derivation approach achieves high accuracy in the selection of efficient and confident collaborators.

SECURED DATA STORAGE AND AUDITING OF DATA INTEGRITY OVER DYNAMIC DATA IN CLOUD
by Santhosh Kumar P
Abstract: Cloud computing is an emerging technology which supports the storage of data via internet. The process of communication is done in an open-access environment and this in turn creates some security and privacy issues which is a real challenge for the cloud users. This facility shoots up the necessity of secure data auditing mechanism over outsourced data. Most of the existing schemes lack the security feature, which can withstand collusion attacks between the cloud server and the unauthorized users. Another most important problem in existing system is data integrity. This paper presents a technique to overthrow the collusion attacks and the data auditing mechanism is achieved by means of vector commitment and backward unlinkable verifier local revocation group signature. The proposed work involves double encryption technique to deal with the privacy measures in cloud server. To extend the security measures a single file has been split into different blocks and stored with different file names. These may leads to the ambiguity for the attackers to trace out the original data. The performance of the proposed work is analysed and compared with the existing techniques and the experimental results are observed to be satisfactory in terms of computational and time complexity.

by Geetha Ramani R, Sivaselvi Krishnamoorthy
Abstract: Automatic region segmentation of brain from the neuroimages is an active research area in the medical domain. Currently, different kinds of Magnetic Resonance Imaging acquisition are performed such that each technique highlights a specific region in the brain making multi-sequence images a better candidate for investigation when compared to single sequence. The abnormal regions (tumor and edema) in glioma images are segmented through hybrid technology involving preprocessing, feature extraction and classification. The extracted features are grouped and random forest procedure is applied on each set and the prediction is obtained that minimizes the randomization. The final prediction of a pixel is obtained by aggregation of individual predictions from feature set through maximum voting which increases the ensembling and improves the outcome appreciably. The average Dice Coefficient of tumor and edema segmentation is 0.96 and 0.94 respectively with 3-fold cross validation. The results show significant improvement when compared to earlier methodologies.

Enhanced Efficient SYN spoofing Detection and Mitigation Scheme for DDoS attack
by Kavisankar Leelasankar, Chellappan C, Venkatesan S, Sivasankar P
Abstract: Protection of critical server from cyber attacks is vital, especially in the case of active attacks like Distributed Denial of Service (DDoS). Attackers start with the Denial of Service (DoS) attack first, since the DoS attack does not need the distributed infrastructure to perform the Distributed Denial of Service (DDoS) attack. A number of attack packets is generated from the single attacking system itself to the victim server, to cause denial of service to the legitimate users. Generally, DoS is an action that prevents or impairs the authorized use of networks, systems, or applications by exhausting the resources, such as central processing units (CPU), memory, bandwidth, and disk space. Seamless services are provided by the constant availability of the server which plays an important factor in providing the customer good Quality of Service (QoS). Monitoring and rate limiting the flow of packets will protect the victim systems by allowing only trusted users during the DDoS attack. The job of the security professionals becomes complex, when the attacks are launched from trusted IP addresses, using Synchronization (SYN) spoofing. The work presented in this paper is experimented with Efficient Spoofed Mitigation Scheme (ESMS) which uses the TCP probing method along with the bloom filter trust model. The experiment is carried out in both IPv4 and IPv6 environment in the SSE (Smart and Secure Environment) real time test bed and the proposed scheme provides accurate and robust information for the detection and controlling of the spoofed packets, during the DDoS attacks.

An Efficient Probabilistic Authentication Scheme for Converging VANET
by HEMAMALINI , Zayaraz , Susmitha Vasanthakumar, Saranya Vadivelu
Abstract: Vehicular Ad Hoc Network (VANET) is the subgroup of the Mobile Ad Hoc Network. VANET interconnects the nodes for transferring secure information between nodes; here vehicle acts as a node. In ACPN, the public-key cryptography (PKC) to the pseudonym generation is used, which ensures legitimate third parties to achieve the non-repudiation of vehicles by obtaining vehicles real IDs. The self-generated PKC-based pseudonyms are also used as identifiers instead of vehicle IDs for the privacy preserving authentication, while the update of the pseudonyms depends on vehicular demands. The Convergence Point (CPA)is used to enable communication when the vehicle is moved out of the particular range, handover scheme occurs. The scheme is used to provide a seamless connectivity. It also provide the secure message transmission. However, adversarial nodes could provide false position information or disrupt the acquisition of such information. Thus, in VANETs, the discovery of neighbor positions should be performed in a secure manner. In spite of a multitude of security protocols in the literature, there is no secure discovery protocol for neighbors positions. We address this problem in our paper: we design a distributed protocol that relies solely on information exchange among one-hop neighbors, we analyze its security properties in presence of one or multiple (independent or colluding) adversaries, and we evaluate its performance in a VANET environment using realistic mobility traces. We show that our protocol can be highly effective in detecting falsified position information, while maintaining a low rate of false positive detections.

A Review of Testing Cloud Security
by Eric Zenker, Maryam Shahpasand
Abstract: The cloud computing paradigm is a nascent technology with many benefits for organisations. The adoption process is constantly advancing as the global revenue for SaaS increased by 14.8% in 2016. On the other side, security of clouds is still one of the major concerns of clients to adopt and use the new computing paradigm. The security of cloud environment underlies three key IT principles: availability, integrity and confidentiality. Likely attacks to cause security breaches are, for example, SQL injections or DoS attacks. One of the most important and effective security measures are encryption and authentication/authorisation to prevent such occurrences. To ensure a high level of security of cloud services and applications, testing is an appropriate approach to detect possible vulnerabilities before real case scenarios occur. In terms of clouds, testing is distinguished in TaaS and testing the cloud. Thus, many academic papers have been published to identify and address challenges in cloud security, vulnerabilities and threats. However, most of the researchers focused on TaaS rather than on testing the cloud, which led to a current gap in academics. This paper presents a systematic literature review of testing cloud security. The authors elucidate a general and consistent topic overview, beginning with defining and introducing key terms. Furthermore, gaps in recent related publications are revealed, hence prospective research implications are pointed out. This survey addresses challenges, vulnerabilities and threats regarding cloud security to foster the understanding and relations of current research fields.

Rearranging links: A Cost-Effective Approach to Improve the Reliability of Multistage Interconnection Networks
by Fathollah Bistouni, Mohsen Jahanshahi
Abstract: One of the main ways to achieve a high computational power is the use of multiprocessor systems. Multistage interconnection networks (MINs) are widely used in parallel multiprocessor systems to connect processors and memory modules. Therefore, design of an efficient MIN is very critical for the construction of high performance multiprocessor systems. On the other hand, reliability is one of the most important performance parameters in the context of interconnection networks. However, hardware cost is a limitation in the design of high-reliable interconnection networks. In this paper, a new approach to improve the reliability of the MINs, called the rearranging links is proposed. The proposed approach is implemented on two common MINs namely extra-stage shuffle-exchange network (SEN+) and augmented shuffle-exchange network (ASEN). Meticulous analysis of terminal reliability proves that the proposed approach is an efficient method to improve the reliability of MINs. In addition, performed cost analysis confirms that utilizing it leads to emerge cost-effective MINs.

by Lamia Allal, Ghalem Belalem, Dhaussy Philippe, Ciprian Teodorov
Abstract: Model checking, introduced 20 years ago, combines several fully automatic techniques in which the property to be checked is tested exhaustively on all the possible executions of the system. It is an automated approach to verifying that a system meets its specifications. The main limit to the use of model checking is related to the state explosion problem, which occurs when the number of states increases exponentially according to the complexity of the system. In this Article, we presented a distributed exploration algorithm executed on two different architectures to fight this problem. The first one is using 2 real machines interconnected across the network and the second using 2 virtual machines in a cloud computing. We carried out a comparative study between these two distributed approaches as well as a parallel approach studied in Allal et al. (2016). The aim of this paper is to give the advantages and drawbacks of each solution.

Fuzzy Based Dynamic Packet Priority Determination and Queue Management method For Wireless Sensor Network
by Maya Shelke, Akshay Malhotra, Parikshit Mahalle
Abstract: The IOT era, where the world is expecting to connect 50 billion devices on internet by 2020, has increased the significance of Wireless Sensor Networks (WSN) manifolds. WSN is made up of large number of resource constrained sensor nodes. Network becomes more valuable when it can be used to its full potential. Hence scheduling of different types of packets, for example emergency real-time, real-time and non-real-time data packets, at sensor nodes in WSNs is of crucial importance to reduce sensors energy consumption, packet loss and end-to-end data transmission delays. Majority of the existing packet scheduling algorithms such as First Come First Serve (FCFS), preemptive priority scheduling and non-preemptive priority scheduling are not adaptive to changes in the data traffic. They also have more processing overhead and large communication delays. In this paper, we propose Fuzzy Based Dynamic Packet priority determination and queue management mechanism (FDMP). In the proposed scheme, each node determines priority of packets dynamically as Gold, Silver and Bronze. Gold packets are placed in high priority queue, silver packets in medium priority queue and bronze packets in lower priority queue. Higher priority packets can preempt medium and lower priority packets, lower priority packets are preempted by medium priority packets. The proposed scheme increases fairness in scheduling packets and energy efficiency by delivering the packets before their expiry (expired packets will not roam around the network), thus reducing network load. The results have been obtained from Network Simulator Version 2 (NS-2) and demonstrate that the enhanced approach outperforms FCFS and Dynamic Multilevel priority queue scheduling algorithms in terms of lower end-to-end delay, throughput, packet delivery ratio and average residual energy.

by Hanen Ahmadi, Ridha Bouallegue, Federico Viani, Andrea Massa
Abstract: The indoor localization of moving target in Wireless Sensor Networks using Received Signal Strength Indicator (RSSI) is addressed in this paper. A novel location tracking algorithm which combines an ensemble learning method and Kalman filter is proposed. An ensemble based regression tree using received signal strength method has been proposed to localize static sensor nodes. In this paper, this approach is employed to solve the complex relation between the RSSI behavior and the target position. Then, the estimated location is introduced in the Kalman Filter as the observed information, leading to more accurate state of the moving target. Experimental results show that the adopted solution achieves a high accuracy compared to localization algorithms currently available in the literature.

by Shivkumar S. Jawaligi
Abstract: In this paper, a robust and efficient delay tolerant and Quality of Service (QoS) oriented data gathering protocol for low power lossy Wireless Sensor Network (WSN) has been proposed. Our proposed routing protocol applied received signal strength based forwarding node selection and transmission path formation scheme, which has been further armored with multiple timer based handoff optimization to enable optimal data transmission, particularly data gathering using single mobile sink node. To ensure backward compatibility of RPL, our proposed scheme has incorporated control message modification that makes our proposed routing protocol applicable for major Low Power Lossy Network commonly known as RPL based Internet of Things (IoT) ecosystem. The higher packet delivery ratio of 98.93% and lower delay and control packet requirements make our proposed routing protocol computationally efficient to be used for major WSN based IoT communication systems.

TRAM Based VM Handover with Dynamic Scheduling for Improved QoS of Cloud Environment
by Nadesh R.K, Aramudhan M
Abstract: The generic view of cloud has seen changes with the entry of cloudlet which combines the servers located in any local area network that can be accessed through any wireless communication. Modern cloud computing has opened avenues for resource and service providers for deployment of their resources irrespective of location. The only issue is the choice of the relevant service provider for the cloud client. There are a number of scheduling algorithms discussed earlier. Resources have been grouped on the basis of various constraints. Yet the methods are unable to achieve the required quality of service parameters. With a view to overcome the issue of previous methods, an efficient TRAM (Throughput-Resource Availability-Makespan) based clustering, VM Handover, with Scheduling is discussed in this paper. The TRAM based approach maintains a list of requests processed on each moment by different cloudlets and groups of the cloudlets according to the TRAM measure. The same TRAM measure is used for making decisions on the handover and scheduling of the request based on TRAM. The recommended approach produces auspicious results on the various qualities of service parameters and produces satisfactory results.

Abstract: Software Development has been inevitable in the modern era. In olden days, organizations followed intense traditional software process; but currently, the focus has turned greatly towards agile methodologies. In agile methodology, Scrum is the mostly followed process. But it comes with a bunch of technical and generic issues. For instance, Assigning, prioritizing and integrating product backlog items prove to be difficult to deal with in agile methodology. On the other hand, it poses several other generic issues ranging from environment problems due to idle team participants and Developer-Tester issues. In this paper mainly concentrates on overcoming the technical issues mentioned above with the assistance of a framework which is perfectly refined in addition to the introduction of a new term called RScrum which is the extension of Scrum which will greatly help to overcome the glitches

Intelligent Intrusion Detection System Using Temporal Analysis and Type-2 Fuzzy Neural Classification
by Rama Prabha Krishnamoorthy Pakkirisamy, Jeyanthi N
Abstract: Cyber-attack detection is an important and challenging area of research inthe field of information technology. In such a scenario, intruders introduce new mechanisms by applying polymorphic mechanisms in order to escape from the intrusion detection systems. This leads to loss in data and increase in security vulnerabilities. In the past, many soft computingtechniques were used from the field of machine learningfor enhancing the efficiency of intrusion detection systems (IDSs) in computer networks. Among them, fuzzy logic playeda major role for making effective decisions. In addition, the neural networks are also contributing more in this area for training the datasets to form rules which can be used to develop an effective intrusion detection system. In this paper, we propose a new intrusion detection system by combining neural networks with temporal and type-2 fuzzy logic for performing effective classification of the dataset. In addition, a new feature selection algorithm is also proposed in this paper which uses information gain of attributes with fuzzy logic decision making for selecting the optimal number of features from the dataset. This work has been tested by using NSL-KDD dataset and through the experiments conducted in this work it is proved that the proposed system increases the intrusion detection accuracy and reduces the false positive rate when it is compared with other existing systems.

BMAQR: Balanced Multi Attribute QoS Aware Replication in HDFS
by Kumar PJ, Ilango P
Abstract: The Hadoop Distributed File system (HDFS) replicates data to ensure data availability in case of a failure caused by events such as data node crash, disk failure, switch/rack failure or corruption in the data block. The evolution of big data leads to large population of data stored and managed in the clusters of cloud. The degree of replication is directly proportional to availability of data with an increase in the replication cost and update cost of data blocks in cloud. The applications executed on the data nodes demand various QoS needs while a block of its data is replicated such as disk access latency, constant bandwidth, delay, jitter etc. Existing replication algorithms replicates data based on the replication factor and the specified QoS needs of application. At a given point of time we expect the types of replication request from different applications varies largely and there is a need to allocate replica based on the request type and the replication factor to achieve a balanced replication cost and availability of data with the available block spaces in the entire cluster. We propose a multi attribute QoS replica allocation algorithm to replicate data considering the different types of replica request, replication factor and the total available space to achieve a balanced replica allocation. The proposed algorithm satisfies different QoS needs of applications and reduces the number of QoS violated replicas when the request consists of different QoS types. We measure the performance of the proposed algorithm in allocating replica and the reduction in number of QoS violated replica count over the existing algorithms such as Random replication. The simulation result shows a better performance over the existing algorithms with a slightly increase in the computational time.

Hilbert Fast-SAMP with Different Channel Estimation Schemes of BER Analysis in MIMO-OFDM system
by Kumutha Duraiswamy, Amutha Prabha N
Abstract: In the OFDM system, there are huge number of sub carrier and high range of signal that produce a very high peak to average ratio reduction (PAPR), so that the signal degrades and further effects the overall Bit Error Rate (BER) performance. The channel estimation techniques are used to avoid much training overhead, that makes an issue in coherent detection. Sparsity Adaptive Matching Pursuit (SAMP) is an existing, thereby the backward pursuit iteration can be repeated for many times, if the support set expands. Due to this iteration, the performance of BER increases, delay occurs and also provides computationally complexity. To avoid the backward pursuit iteration, Hibert-fast sparsity adaptive matching pursuit (HF-SAMP) is proposed which reduces the computational complexity and decreases the BER performance to the maximum extent. Zero padding is also appended, results in better improvement of BER performance. The performance of BER, SNR, MSE and PAPR using the Channel Estimation (CE) and Pilot Design (PD) techniques are analyzed and the proposed technique yields better and thereby performance rate increases than the other existing conventional algorithms. MATLAB is used for performing the simulations.
Keywords: CE; HF-SAMP; OFDM; BER; PAPR; Pilot Estimation; ZP and SOMP.

A Scalable Fine-Grained Analytic Model for Container Cloud Data Centers
by Bingwei Liu, Yu Chen
Abstract: Cloud Computing is today's main-stream computing paradigm because of many attractive features. Although Cloud service providers have deployed numerous large scale Cloud data centers around the world, research in performance modeling for Cloud data centers are still in its infancy. A precise model of a Cloud data center can help the service providers improve their service quality, capacity planning, load balance and reduce operation costs. Most studies in literature focused on modeling hypervisor based cloud, typically IaaS. With the growing popularity of containers in Cloud service providers, there is a need to develop performance models specifically for these systems. A novel Cloud analytic model (CAM) for container-based Cloud data center was proposed. In the model, all schedulers in the Cloud logical hierarchy are modeling as unified Markov Chains with different model inputs. We identified the process at a scheduler as a Quasi-Birth-Death (QBD) process and provided algorithmic solutions using matrix-geometric analytic methods for infinite and finite cases. Physical machines (PMs) are modeled differently due to their underlying characteristics. CAM was able to capture the critical features in the Cloud. We utilized these interactive stochastic models to analyze the performance of the system in terms of mean job delay and probability of job rejection. Finally, a Container emulation framework, ConSim, was developed and tested against the analytic model. ConSim runs on actual container Cloud hardware and measures desired performance matric such as number of rejected jobs and delay of each job. Experimental development using real data were compared with theoretical calculation. The results showed promises in using the proposed analytic model to help service planning in container Clouds.

DEADLINECREDIT AWARE HEURISTIC FOR DYNAMIC RESOURCE PROVISIONING IN A VIRTUALIZED CLOUD ENVIRONMENT
by Kamali Gupta, Vijay Katiyar
Abstract: Cloud computing as a paradigm has led to its adoption in large scale
parallel processing and distributed computing. The consumer's computational
needs serviced by the providers resulted in significant rise in its demand as latest
services can be accessed with different pricing models, value-added features
and instance types. Resource selection is a tedious task and places momentous
challenges of resource management before consumers and service providers.
As a remedy to this vanguard issue, brokers stipulates resource provisioning
options to ease the task of selecting the best resource that can match the
submitted requests by facilitating a standardized management interface across
Keeping in consideration this point, a Deadline-Aware Sufferage (DSufferage)
algorithm is proposed and implemented at platform level in this research work.
The algorithm is an improvisation in the existing sufferage heuristic. Deadline
parameter has been inculcated to assign precedence levels to the jobs to be
submitted to the machines apart from minimum completion time. The novelty of
the current research study is that the heuristic is centered towards both user and
providers goals in comparison to the existing batch-mode heuristics. The efficacy
of the algorithm has been verified using CloudSim tool and is concluded that
it is proficient enough to allocate resources to users tasks with in constraints of
deadline, resource utilization maximization and SLA violation avoidance.

Financial Default Payment Predictions Using A Hybrid of Simulated Annealing Heuristics and Extreme Gradient Boosting Machines
by Bichen Zheng
Abstract: Online Peer-to-Peer (P2P) lending platforms face multiple challenges in today's e-commerce, but one of the most outstanding concerns evaluating loan risk based on borrowers' financial status and histories. Traditionally, financial experts assess borrowers' risk of default payments manually, but this process is tedious and time consuming, which are not widely applicable concerns for online P2P platforms. This paper proposes a hybrid of the Simulated Annealing and the Extreme Gradient Boosting Machine models in order to predict the likelihood of default payments based on users' finance histories. Based on the experimental results, the proposed model demonstrates its predictability with high recall scores. The proposed model not only out-performs over conventional algorithms including Logistic Regressions, Support Vector Machines, Random Forests, and Artificial Neural Networks, but it also provides an efficient method for optimizing hyper-parameters in the machine learning algorithms. Through the utilization of the proposed data-driven models, the necessity of tedious and potentially inaccurate human labor can be significantly reduced, and service level agreements (SLAs) can be further improved by time reduction made possible through the introduction of advanced data mining approaches.

Outlier Detection Techniques for Big Data Streams: Focus on Cyber Security
by Fatima-Zahra Benjelloun, Ayoub AIT LAHCEN, Samir Belfkih
Abstract: In recent years, detecting outliers in Big Data streams has become a main challenge in several domains (i.e., medical monitoring, government security, information security, natural disasters, and online ﬁnancial frauds). In fact, unlike regular static data, streams raise many issues like high multidimensionality, dynamic data distribution, unpredictable relationships, data sequences, uncertainty and transiency. Most of the proposed approaches can handle some of these issues but not all. In addition, they provide limited considerations with regard to scalability and performance. Real-world applications require high performance, resources optimization and real-time responsiveness when detecting outliers. This is useful to extract knowledge, detect incidents and predict patterns changes. In this paper, we review and compare recent studies in detecting outliers for streaming. We investigate how researchers improved the outcome of different models and monitoring systems, especially in the context of cyber security.

Improving Cloud Computing Services Indexing based on BCloud-Tree with Users Preferences
by Ahmed Khalid Yassine SETTOUTI, Fedoua DIDI, Mohammed HADDAD
Abstract: Wireless Sensor Networks and Cloud Computing are different but complementary. In a hand, the wireless nodes are resources limited and battery constrained. In the other hand, Cloud computing is unlimited in terms of computing, storage, network and power resources. Integrating such different concepts results obviously some troubles; especially for WSN owners who want to pick up the most suitable Cloud Computing provider. In addition, we suppose that both of the clients (WSN owners) and services are heterogeneous, various and dissimilar. In this paper, we propose an indexation method of public IaaS virtual machines in an AVL-Tree. For that, we employ a Z-order function to arrange services in the structure and make the research more efficient. Experiments prove the performance superiority of the proposed approach in comparison with similar works in the literature.

Autonomic Resource Management Framework for Virtualized Environments
by Raman Bane, Annappa B.
Abstract: Virtualization enables multiples Virtual Machines (VMs) in a sense multiple Operating Systems to co-locate on a same physical machine with total isolation. Hence using VMs to launch web services or applications is the common trend nowadays in enterprise Information Technology (IT). Data Center provides infrastructure to create, configure and manage VMs. It includes autonomic computing, a scenario in which the data center environment will be able to manage itself based on perceived activity and demands for different resources. It has seen as a utility that clients can pay for only as needed.
The growing complexity of modern networked computer systems with Virtualization Technology necessitates the need for analysis of the performance of these systems concerning resource management. We have developed an intelligent resource manager which uses statistical learning methods to control the resource allocation in Xen virtualized environment for dynamically allocating resources to individual VM. Our resource management architecture comprises of fuzzy logic based local and global controllers.
Experimental results show that with the proposed system data center can efficiently allocate CPU resources to VMs that have been produced by customers. The scaling of CPU resources is automatically done in accordance with the dynamically changing workload at a minimum granularity of 2 seconds. It improves the resource utilization by 30% as compared to the ideal method while maintaining throughput as equivalent to the ideal workload allocation.

by Rajani Kumari, Dinesh Kumar, Vijay Kumar
Abstract: The optimization of multi-objective problems is currently an important area of research and development. The importance gained by this type of problem has given rise to the development of multi-objective metaheuristics to attain solutions for such problems. In this paper, an experimental comparison of NSGA II (Nondominated Sorting Genetic Algorithm II), AbYss (Archive-Based hYbrid Scatter Search), and OMOPSO, (Optimized Multi-objective Particle Swarm Optimization) using ZDT benchmark, has been done to determine which multi-objective metaheuristic has the best performance with respect to a problem.

MDI-SS: Matched Filter Detection with Inverse covariance matrix based Spectrum Sensing in Cognitive Radio
by Budati Anil Kumar, P. Trinatha Rao
Abstract: Spectrum Sensing has been a major issue while dealing with the Cognitive Radio (CR) Networks. Predominantly the situation arises where noise is falsely interpreted as primary user signal. This type of interpretation is called probability of false alarm (Pfa). As per the available literature, Matched Filter Detection (MFD) and Neyman Pearson (NP) observer approaches are few methods used to identify the Pfa. The user presence is estimated based on the parameters Pfa, probability of detection (PD), Threshold and Receiver Operating Characteristics (ROC). The method which is in existence, MFD measures ROC with different algorithms and suggests that by using NP observer to improve the PD and minimize the Pfa. Which leads to the problem as identified, for which samples the Pfa is affected. The presence or absence of the user is identified by evaluating the threshold namely Pfa and PD. Generalized Log Likelihood Ratio Test (GLRT) is used to measure the threshold. The estimation of the accurate threshold value inverse covariance matrix approach is added to MFD and framed as Matched Filter Detection with Inverse covariance matrix based Spectrum Sensing (MDI-SS). As per the threshold values, PD and Pfa is evaluated for NP observer and MDI-SS. An attempt is made to improve the PD by MDI-SS and compare with the existing MFD algorithm. The Pfa affected samples are identified with reference of NP observer, by employing the parameters of PD, Pfa, thresholds are measured at different SNR levels and comparative analysis has been proposed between MDI-SS with NP observer. The PD, Pfa, ROC results are observed by implementing on MATLab software.

Prevention of a SYNflood attack using Extreme XOS Modular Operating System
by BHAKTHAVATSALAM P.K, THAVAMANI SHANMUGAM, MALARKODI B
Abstract: Network security has become a critical concern for protecting systems from attackers. Even though by securing these systems, a skilled attacker may use some techniques to launch a sophisticated attack. SYNflood attack is the commonly evolving attack which is a form of Denial of Service (DoS) attack, where an attacker sends SYNflood in a form of request to the targets system in a successive manner causing the system unresponsive to the legitimate request. Thereby, this attack causes bandwidth congestion by reducing the processing capability of network systems and servers. In this paper, we proposed a scheme for preventing SYNflood based on statistical parameters of incoming traffic using the hard threshold method which is implemented by using Extreme XOS software. It is a software embedded with the switch for controlling network traffic statistical parameters.

by Mohammed Salman Arafath, Khaleel Ur Rahman Khan, K.V.N. Sunitha
Abstract: Wireless ad-hoc and sensor networks (WASN) or opportunistic sensor networks (Oppnets) have been improving their availability in providing secure communication between military candidates in military applications. The existing work has not addressed this issue effectively. This paper proposes secure route selection and three different encryption algorithms for Commando-Commando (CC), Soldier-Soldier (SS) and Commando-Soldier (CS) communication. Routing is based on path protected hop-by-hop routing protocol (PPHH) by which a secure path is selected with authentication by certificate authority (CA). The cryptography algorithms used are code-based cryptography, hyperelliptic curve cryptography, and design-based cryptography. The proposed strategy in this paper shows improvements in security, energy consumption, throughput, packet overhead and network reliability.

Blind Spot Monitoring at Night-time using Rear-View Camera
by Seon-Geol Kim, Kang Yi, Kyeong-Hoon Jung
Abstract: The Blind Spot Monitoring (BSM) is one of the key functions of Advanced Driver Assistance System (ADAS). In this paper, we propose a vision-based blind spot detection and tracking algorithm which is applicable at night-time. The feature of highly bright blobs due to the headlights of behind vehicle is employed for the detection of vehicles in blind spot area, because the appearance-based approach that can be used at daytime is not any more appropriate. We calculate the motion vectors of detected blobs to find an approaching vehicle and make headlight pairing to estimate its position by use of the projection map. We can successfully generate an alarm signal by detection and tracking the overtaking vehicle in blind spot area at night-time.

An Auto-Configuring Mesh Protocol with Proactive Source Routing for Bluetooth Low Energy
by Julio León, Abel Dueñas, Cibele Makluf, Frank Cabello, Guillermo Kemper, Yuzo Iano
Abstract: The Internet of Things (IoT) is spreading rapidly towards creating smart environments. Wireless sensor networks (WSN) are among the most popular applications discussed in IoT literature, with most of them considering many forms of wireless mesh communications. One of the most available and popular wireless technologies for short-range operations (yet not designed for mesh) is Bluetooth. Literature shows some studies on mesh networks BLE, based on Bluetooth 4.1 (which supports Master/Slave Multirole). Those approaches require more powerful hardware than a simple wireless sensor peripheral.rnNonetheless, none address dynamic address allocation and topology mapping for BLE. rnWe propose a new autoconfiguring dynamic address allocation scheme for a BLE Ad-Hoc network, and a network map discovery mechanism that doesn't require role changing, compatible with BLE 4.0 or later versions.

Light Field Compression on Sliced Lenslet Array
by Cristian Perra, Daniele Giusto
Abstract: Recent advances in light field technologies is fostering the research and development of novel imaging applications. Such applications perform processing of the light field information to create new visual effects such as, for example, refocusing, perspective change, colour adjustment. Light field imaging is very data intensive compared with usual digital photographic imaging, and novel compression algorithms are needed for addressing the problem of light field storage and transmission. Raw digital light field images exhibit low spatial correlation if compared to regular images and hence the performance in terms of rate-distortion of current state-of-the-art image encoders can be superseded by devising novel image compression architectures. In this paper, an architecture for lossy compression of unfocused light field images is proposed. Raw light fields are preprocessed by demosaicing, devignetting and slicing of the raw lenslet array image. The slices are then compressed with the JPEG 2000 image coding standard. The performance of the proposed method is compared against direct application of JPEG 2000 compression on the 4D light field. The experimental analysis has been conducted under a set of different compression ratios and the obtained results show that the proposed method outperforms direct application of the reference architecture.

Variable Switching Frequency Control for Active Cell Balancing Systems
by SANGWON LEE, JAEJUNG YUN
Abstract: A new active cell balancing control method is presented for improving the active cell balancing speed of a Li-ion battery pack. The proposed method calculates the switching frequency based on the sensed charging/discharging current of the battery pack. It then modulates the balancing power of the active cell balancing circuit within the value of the charging current limit and discharging current limit. The method can achieve high balancing performance without much computational work and additional power electronic components. A multi-cell balancing algorithm is also introduced for using the proposed method in an actual battery management system, which was verified by PSIM simulations with an irregular profile of the battery load current. The proposed method shows faster balancing speed than a conventional cell balancing method with a fixed switching frequency.

Software Framework for Runtime Application Monitoring of fail-safe multi-processor ADAS SoCs
by Piyali Goswami, Kedar Chitnis, Brijesh Jadav, Ashish Kapania, Shiju Sivasankaran
Abstract: In Advanced Driver Assistance (ADAS) systems, it is very critical to ensure a system malfunction does not cause harm to humans (also referred to as functional safety). Malfunctions could occur due to incorrect software (SW) execution. Many techniques exist to catch systematic SW faults during software and application development. However, without run-time monitoring of key parameters, it is impossible to guarantee a fail-safe system. In this paper, we describe a software framework to monitor application statistics in heterogeneous multiprocessor SoCs targeted for fail-safe ADAS systems. With <0.5% CPU load overhead per monitor, the proposed framework was found to accurately report statistics for a front camera analytics application.

Abstract: This paper exhibits a risk-based philosophy in cloud computing to estimate ideal quality and maintenance which maximise the high availability of cloud administration infrastructure. The procedure is confined into two stages: 1. accessibility displaying the cloud frameworks, 2. Hazard based assessment and maintenance estimations. The technique is easy but difficult to apply and needs promptly accessible information in a cloud environment. The approach can be further improved by comparing the existing inspections with the previous consequences of reviews. The projected procedure is practical to the health care scheme using Markov chain process.

Cost Based Constrained Task Scheduling in Cloud Environment
by AR.ARUNA RANI, Dr.D.MANJULA
Abstract: In recent years the most important requirement in the cloud computing environment is the task scheduling which is the key role for efficiency in sharing of cloud resources among multiple users. Cloud provider is always assumed to own its large data centre which has significant computational resources with it. In the cloud environment all the tasks are allocated and executed by using the available services in order to achieve higher performance, least total time for computation, shortest period of response time and utilization of resources and so on. There are some serious challenges that the existing models could allocate the task to the resources without the profit maximization scheme. The main motivation that is behind this paper, is to design and to develop a CLOUD manager(CM) to efficiently manage the cloud resources and also completing the jobs for the allocated resources for the given task in the cloud environment. It is implemented using a prior resource optimization (PRO) based allocation algorithm that takes into account execution time, transmission time and cost. The desirable feature of this paper is that the resources are allocated as per the cloud consumer request. The potency of this is presented in the cloud environment by finding the optimal and suboptimal allocation scheme of resources which maximize the profit of cloud provider and also improve the quality of scheduling solution.

An Efficient Spectrum Handoff Decision Making Scheme for Cognitive Radio Networks
by Preetha K S, Kalaivani S
Abstract: There has been a gigantic spike in the usage and development of wireless devices since the time wireless technology has come into existence. This has contributed to a very serious problem of spectrum unavailability or spectrum scarcity. The solution to this problem comes in the form of cognitive radio networks where the secondary user which is also known as the unlicensed users makes use of the spectrum in an opportunistic manner. The secondary user uses the spectrum in a manner such that the primary or the licensed user doesnt face interference above a threshold level of tolerance. Whenever a primary user comes back to reclaim its licensed channel, the secondary user using it needs to perform a spectrum handoff to another channel which is free of primary user. Our primary focus is on performing spectrum handoff decision making. The SU selects staying or changing policy based on the average extended delivery time. The spectrum handoff decision making is performed, i.e. the optimal channel for spectrum handoff is decided only if changing policy is adopted which is based on Multiple Attribute Decision Making (MADM). This spectrum handoff decision making scheme is later extended using Artificial Neural Networks (ANN) and probabilistic Markov Model.

Enhancing Network Lifetime through Power-aware Routing in MANET
by Rakesh Kumar S, Gayathri N, Balamurugan Balusamy
Abstract: Mobile Ad hoc Network (MANET) is a self-organized network that allows communication between the nodes that are in radio range of each other. MANET nodes can join and leave the network dynamically, leading to a rapid change in network topology. As not all nodes in MANET are in radio range of each other, the intermediate nodes help in routing of the packets. The packets are transferred from the source node to the destination node over the network. As the nodes in MANET are battery powered, the intermediate nodes may at times lose its power completely which might lead to partitioning of the network. Hence, the communication between the nodes might get disconnected and thus the lifetime of the network gets reduced. Thus, the limited power resource is one of the major disadvantages here, as the batteries cannot be recharged or replaced in many of the locations where MANETs are deployed. This work is aimed at providing a solution mechanism that efficiently utilizes the existing power resources in MANET nodes thereby extending the lifetime of the network.

Privacy Preserving Computation of Scalar Product and Sign of Scalar Product
by Subrata Bose, Asim Pal
Abstract: Scalar product is repeatedly used in a large family of applications. It is a useful building block of many scientific and business applications. Secure scalar product computation is widely used in many privacy-preserving computation domains. In this work we have proposed privacy preserving protocols for computing scalar product or only its sign. These protocols work on two basic principles random data perturbation and algebraic methods, and thus avoid standard encryption/decryption overheads. We have designed the protocols to get sign of the scalar product, which can act as a basic building block in privacy preserving database queries over distributed databases and many other applications. We have developed two sets of protocols for the two-party computation with and without using an untrusted third-party. Experimental results on generated random datasets show that the proposed protocols indeed involve low communication overhead.

by Premalatha T, Duraisamy S
Abstract: Internet of thing (IoT) is the important concept for making the effective and secure communication between the networks. During the communication process the security and intermediate attack is one of the main issues because the communication may be used in the various applications such as energy management, infrastructure analysis and environmental monitoring process so on. This issue has been overcome by applying the effective transmission protocol along with the secure encryption method. Initially, communication process is enhanced and making reliable with the help of the Media Gate Network Transmit protocol along with the reliable data transport protocol. In addition, the intermediate attacks present in the network communication process have been resolved by using the fuzzy soft multi-set blowfish encryption method. The application layer transmission protocol with the encryption method ensures the secured communication when compared to the other protocol based communication. Then the efficiency of the system is evaluated with the help of the experimental results in terms of the energy consumption and throughput metrics.

Abstract: High bandwidth routing is the most desired advantage in networks with portable nodes. The main objective of this work is to obtain a high bandwidth route for increasing the delivery rate in MANETs. Dynamic high bandwidth (DHB) nodes are picked for data transmission in MANETs. A measure from the current packets received by a node and the packet delay and the bandwidth are used to calculate the total transmission efficiency of a node. Thereby the routes are identified by this dynamic estimation to improve routing capability in MANETS. Analysis of the performance of the protocol is carried out by using the network simulator (NS-2).
Keywords: Routing; bandwidth; mobile ad hoc networks; performance analysis.

An Integrated Approach For Network Traffic Analysis Using Unsupervised Clustering And Supervised Classification
by Chokkanathan Kothandapani
Abstract: Traffic classification and analysis is a significant task to control the network traffic in a heterogeneous manner. The unsupervised learning system or network environment fails to expand the supervised classification model for network analysis. The several data mining techniques identified the network traffic pattern and classified the network traffic accurately using unsupervised learning approach. However, the continuous evaluation of network traffic on multi-dimensional data is a difficult task in real time data traffic. In order to overcome the problem in traffic analysis, An Integrated K-means Unsupervised Clustering and Supervised C4.5 Classification (KUC-SC) technique is introduced. An integrated technique is used to evaluate the network traffic conditions to classify the patterns of real time and non-real time traffic. An integrated KUC-SC technique performs two types of processing steps such as clustering and classification. At first, K means unsupervised learning algorithms is applied in KUC-SC technique to form a k number of clusters using the different input data point with the nearest mean. The clustering approach is used for classifying the given data. After that, C4.5 is used to classify the data whether it is real time or non-real time traffic through the construction of decision-tree. At every node of the tree, C4.5 algorithm classifies the data point that most efficiently divides the set of samples into subsets with similar characteristics. This in turn improves the classification accuracy in network traffic data analysis. An experimental result shows that the proposed KUC-SC technique obtains the better performance in terms of classification accuracy, classification time, true positive rate and communication overhead compared to the state-of-the-art works.

Response Time Based Resource Allocation According to Service Level Agreements in Cloud Computing
by G. Hemanth Kumar Yadav, K. Madhavi
Abstract: Cloud computing is a technology which offers various services as and when required by the user through various cloud providers. The scalable nature of cloud has made it to reach various domains and have a strong root in every organization. The resource provisioning has become a challenging task for many cloud providers. This work proposes an efficient framework for handling storage, application and computation services, offering Service-Level Agreements (SLA) backed performance and uptime promises for their services in cloud computing .Further this tries to benefit both the users as well as cloud providers by enhancing the features for the customers and by gaining profit for the providers. The proposed SLA based resource provisioning system is found to perform better than the existing other resource provisioning systems in terms of response time and other QoS parameters.

Managing Incident Response in Industrial Internet of Things
by Allan Cook, Leandros Maglaras, Richard Smith, Helge Janicke
Abstract: Industrial control systems are an essential element of critical national infrastructure, often managing processes and utilities that are essential to a nation's well being and prosperity. These systems are increasingly becoming the target of cyber attacks, and as a result are required to adopt a stronger cyber defense posture. In the next years, the Internet of Things revolution will dramatically alter manufacturing, energy, agriculture, transportation and other industrial sectors of
the economy. Industrial Internet of Things(IIoT) will bring new opportunities to business and society, along with new threats and security risks. However, much of the technology within a control system is based on proprietary devices optimized for performance at the expense of security and does not necessarily integrate well into an overall defense-in-depth architecture. Similarly, the control system technology does not readily support the processes and procedures found in IT incident response plans. In this paper we explore the characteristics of an industrial control system and consider them within the framework of an established incident response framework by Prosise at al. We conclude that existing incident response processes are applicable to industrial control systems, but their nature must be modeled, especially in the pre-incident phase of planning, in order to accommodate the idiosyncrasies of such technologies. We recommend that these models be developed and tested within synthetic environments to test and quantify cyber attack impacts and drive architectural improvements and incident response investment.
