    by Aniruddha Bhattacharjya, Xiaofeng Zhong, WANG JING 
    Abstract: In Future Internet Architectures, End to End (E2E) secured personal messaging is essential. So here an E2E user two way authenticated double encrypted messaging architecture based on Hybrid RSA for private messaging is proposed. Our P2P protocol works over TCP protocol for creating direct connections in between, with IPv4 broadcast options to discover peers on the same LAN. Our protocol implements Perfect Forward Secrecy using DiffieHellman key exchange with re-negotiation capability in every session with Optimal Asymmetric Encryption Padding and random salts. For making Hybrid RSA with double encryption, in encryption level, main RSA is integrated with efficient RSA to give more statistical complexity. In the decryption process, the CRT is used for very high efficiency with integration with Shared RSA. Our architecture also gives a hassle-free, secure, Peer-to-Peer, strong and reliable platform with E2E encryption for private messaging and it can work with Future Internet Architectures also.

    Abstract: Steganography is a technique of hiding information imperceptibly inside other medium so that the very fact of communication taking place remains hidden. Recently, the reach of Internet has extensively widened through social networking and blogging websites and a high amount of digital media interchange, especially in the form of digital images is being witnessed. This poses a huge threat to security from hackers and terrorists, as this medium can be used for covert communication, thus justifying the need for good steganalysis techniques to detect the existence of hidden messages in digital images. This paper analyzes some steganalysis techniques which attack various kinds of Spatial Domain Steganography techniques. Some of them are Chi-square attack, Triples Analysis, Sample Pair analysis, TPVD steganalysis and Analysis of Adjacent Pixel Pair steganalysis. This paper also identifies the current research challenges and discusses possible directions for future research in this field.

  • Modelling A Secure Support Vector Machine Classifier For Private Data   Order a copy of this article
    by Sumana Maradithaya 
    Abstract: Privacy preserving data mining engrosses in drawing out information from distributed data without disclosing sensitive information to collaborating sites. This paper aims on the construction of a vertically distributed privacy preserving support vector machine classifier. The learning model is build for datasets, where one of the collaborating parties comprises the dependent attribute. Furthermore, the amount of privacy, computation speed and the accuracy of our classifier outperform other benchmark algorithms while modelling support vector machine classifier retaining privacy. Privacy of the data distributed at multiple sites is maintained by performing secure computations. The perceptive attributes values of the cooperating sites are unknown to the other sites. Collaborative classification is performed using these attributes. The site with the dependent attribute is the master site that initiates the process of secure computation to identify support vectors. Homomorphic property is used to protectively compute the data matrix on records/tuples available at sites. The recommended nonlinear privacy preserving classifier provides an accuracy equivalent to the non privacy undistributed SVM classifier which uses all the attributes directly.

    Abstract: Intrusion detection system protects an individual computer or network computer from suspicious data and protects the system from unauthorized access. On the other hand, feature selection is necessary in the case of high dimensionality data. In this paper, we propose a Feature Selection Technique (FST) known as Sensitivity Based Feature Selection Technique (SBFST) which selects relevant features from intrusion data based on the value of sensitivity, which is an important classification measure to evaluate a classification model more accurately. We also compare various existing FSTs with the proposed technique from NSL-KDD data set. Experimental work is conducted using three different categories of NSL-KDD data sets: (i) Binary class problem with normal and Denial of Service (DoS) (ii) Binary class problem with normal and attack and (iii) Multiclass problem with normal and four types of attack. The proposed FST, as well as existing FSTs with C4.5 decision tree classifier, have been applied to these three different categories of NSL-KDD datasets using different partitions. Experimental results at testing stage reveal that SBFST performs better than other existing FSTs. C4.5 with SBFST produce a high accuracy of 99.68% and 99.95% for the multiclass problem and binary class problem respectively. The performance of proposed technique is also verified using the intersection of features, segment by segment with other FSTs and found to be better.

  • Assessing Cyber-Incidents Using Machine Learning   Order a copy of this article
    by Ross Gore, Saikou Diallo, Jose Padilla, Barry Ezell 
    Abstract: One of the difficulties in effectively analyzing and combating cyber attacks is an inability to identify when, why and how they occur. Victim organizations do not reveal this data for fear of disclosing vulnerabilities and attackers do not reveal themselves for fear of being prosecuted. In this paper, we employ two machine learning algorithms to identify: (1) if a text-based report is related to a cyber-incident and (2) the topic within the field of cyber-security the incident report addresses. First, we evaluate the effectiveness of our approach using a benchmark set of cyber-incident reports from 2006. Then, we assess the current state of cyber-security by applying our approach to a 2014 set of cyber-incident reports we gathered. Ultimately, our results show that the combination of automatically gathering and organizing cyber-security reports in close to real-time yields an assessment technology with actionable results for intelligence and security analysts.

  • High frequency implementation of cryptographic hash function keccak-512 on FPGA devices   Order a copy of this article
    by Soufiane El Moumni, Mohamed Fettach, Abderrahim Tragha 
    Abstract: Cryptographic hash functions have an important role in numerous cryptographic mechanisms like computing digital signatures, checking data integrity, storing passwords and generating random numbers. Due to the cryptanalysis attacks on hash functions, NIST expressed its need to a new resistant hash function by announcing a public competition, this competition made Keccak hash function the new secure hash algorithm SHA-3. This new SHA-3 proved its strengths against recent attacks, however it has to be implemented efficiently in order to keep its resistance. In other words, an efficient FPGA design of hash functions is needed, be it increasing frequency, minimizing area consumption, or increasing throughput. In this paper we have focused on increasing frequency of the keccak-512, and we have achieved 401.2 MHz as a maximum frequency, and 9.62 Gbps as a throughput. The proposed design has been implemented in Xilinx Virtex-5 and Virtex-6 FPGA devices and compared to existing FPGA implementations.

  • Innovative Data Security Model Using Forensic Audio Video Steganography for Improving Hidden Data Security and Robustness   Order a copy of this article
    by SUNIL MOON 
    Abstract: Data embedding using steganography is not a major issue but recovery of hidden data in a secured way without degradation of both original and secret data are the major problem. To the best of our knowledge many researchers are working on image steganography using (Exploited Modified Direction) EMD algorithm to improve the hiding capacity and security. But nowadays internet is mostly popular due to Face book, YouTube and WhatsApp which consists of videos; hence in this paper we have proposed a combination of video crypto-steganography and digital forensic technique using Modified General EMD (MGEMD) algorithm for enhancing the embedding capacity and security of secret data. We have embedded the secret data as an image and audio behind the selected frames of video and obtained the key security parameters using forensic technique to improve the hiding capacity and the data security which is found to be better than any other existing methods.

  • Detection Algorithm for Internet Worms Scanning that Used User Datagram Protocol   Order a copy of this article
    by Mohammad M. Rasheed 
    Abstract: The Internet pervades almost every aspect of our lives. Also, with the development of network technologies and applications, worm attacks greatly affect the network infrastructure security and safety. As a key technique in network security domain, Intrusion Detection System (IDS) plays a vital role of detecting various kinds of worm scanning. The main purpose of IDS is to find out intrusions among normal audit data and this can be considered as a classification problem. This problem is brought about by the User Datagram Protocol (UDP) which is a connectionless protocol that means it does not require a formal handshake to get the data flowing and has no need for SYNs, ACKs, FINs flags, or any other handshaking. With UDP protocol, the packets are sent and received without warning, and previous notice is not usually expected. Worms also make use of UDP protocol to connect or scan with other hosts. In this research, UDP Scanning Worm Detection (UDPSWD) was proposed to detect UDP worm scanning by checking the failure message connections. UDPSWD focuses on The Internet Control Message Protocol (ICMP) unreachable, ICMP time exceeded and UDP is not responded to. The results show that UDPSWD is faster in comparison to other techniques, with no false positive or negative alarm.

  • SPHERES: An Efficient Server-side Web Application Protection System   Order a copy of this article
    by Ouissem Ben Fredj 
    Abstract: While the web attacks grow in number and manner, the current web protection methods fail to follow this evolution. This paper introduces a new design of a Web application protection method called SPHERES. The main idea behind SPHERES is that it is placed in the application server, it intercepts the decrypted traffic, and checks it against a set of filtering rules specific to the requests. This design allows SPHERES to have the most accurate picture of the exchanged traffic, the websites structures and workflows, the user sessions and their states, and the system states. This accurate picture of the total system allows SPHERES to build a protection sphere around the website and checks several types and levels of protections efficiently. In addition to the detection of known attacks, SPHERES is able to detect zero-day attacks at runtime. The performance study of SPHERES shows that it is much better than two famous existing web protection tools.

  • A novel verifiable and unconditionally secure (m,t,n)-threshold multi-secret sharing scheme using Overdetermined systems of linear equations over finite Galois fields   Order a copy of this article
    by Faraoun Kamel Mohamed 
    Abstract: Threshold multi-secrets sharing schemes allow sharing a set of m secrets among n participants, while secrets can be revealed only if t or more participants collude. Although many multi-secret sharing schemes have been proposed, several improvements remain essential in order to cope with actual effectiveness and security requirements, including computational performances and compliance for large-scale data. In this paper, we present a novel multi-secrets (m,t,n)-threshold scheme using overdetermined systems of linear equations defined over finite Galois fields. The scheme provides unconditional security, linear sharing /reconstructing complexities and holds secure verifiability and t-consistence. By considering both secrets and shares as elements over finite Galois fields GF(2r), optimal and space-efficient representation is ensured compared to recent sharing schemes. In addition, the scheme provides dynamic secrets sharing, forgery/cheating detection and robustness against common attacks, while lower computational overhead is required.

  • A generic construction of identity-based proxy signature scheme in the standard model   Order a copy of this article
    by Xiaoming Hu, Huajie Xu, Jian Wang, Wenan Tan, Yinchun Yang 
    Abstract: Recently, numerous identity-based proxy signature (IDPS) schemes are constructed by direct methods or generic methods. However, most of them are proved only to be secure in the random oracle model or are involved high computational cost. In this paper, we present a novel and generic construction method of IDPS scheme secure in the standard model from any identity-based signature (IDS) scheme. The security of IDPS scheme constructed by our method is based on the security of the original IDS scheme. The computational cost of constructing an IDPS scheme is almost the same as that of constructing an original IDS scheme. Compared with other existing IDPS schemes constructed by direct methods or other generic methods, our IDPS scheme has better performance: the signature length and the computational cost of our IDPS scheme are almost half of other existing IDPS schemes. What's more, our method can be applied to construct other identity-based proxy cryptosystems.

  • Outsourcing Computation for Private Function Evaluation   Order a copy of this article
    by Henry Carter, Patrick Traynor 
    Abstract: Outsourcing secure multiparty computation (SMC) protocols has allowed resource-constrained devices to take advantage of these developing cryptographic primitives with great efficiency. While the existing constructions for outsourced SMC guarantee input and output privacy, they require that all parties know the function being evaluated. Thus, stronger security guarantees are necessary in applications where the function itself needs to be kept private. We develop the first linear-complexity protocols for outsourcing private function evaluation (PFE), a subset of SMC protocols that provide both input and function privacy. Assuming a semi-honest function holder, we build on the most efficient two-party PFE constructions to develop outsourced protocols that are secure against a semi-honest, covert, or malicious Cloud server and malicious mobile devices providing input to the function. Our protocols require minimal symmetric key operations and only two rounds of communication from the mobile participants. To make these protocols possible, we develop a technique for combining public and private sub-circuits in a single computation called partially-circuit private (PCP) garbling. This novel garbling technique allows us to apply auxiliary circuits to check for malicious behavior using only free-XOR overhead gates rather than the significantly more costly PFE gate construction. These protocols demonstrate the feasibility of outsourced PFE and provide a first step towards developing privacy-preserving applications for use in Cloud computing.

  • An Ensemble Algorithm for Discovery of Malicious Web Pages   Order a copy of this article
    by Hedieh Sajedi 
    Abstract: Internet has become one of our daily life activities that all of us agree on its important role. It is necessary to know how it can either have misuse. Identity theft, brand reputation damage and loss of customers confidence in e-commerce and online banking are examples of the damages it can cause. In this paper, we proposed an ensemble learning algorithm for discovery of malicious web pages. The goal is to provide more learning chance to the data instances, which are misclassified by previous classifiers. To this aim, we employ a Genetic Algorithms (GA) to improve classification accuracy. In this algorithm a weight is assigned to a weak classifier and GA chooses the best set of committee members of weak classifiers to make an optimal ensemble. Experimental results demonstrate that this algorithm leads to the classification accuracy improvement.

  • PrivacyContext: Identifying Malicious Mobile Privacy Leak Using Program Context   Order a copy of this article
    by Xiaolei Wang, Yuexiang Yang 
    Abstract: Serious concerns have been raised about users privacy leak in mobile apps, and many detection approaches are proposed. To evade detection, new mobile malware starts to mimic privacy-related behaviors of benign apps, and mix malicious privacy leak with benign ones to reduce the chance of being observed. Since prior proposed approaches primarily focus on the privacy disclosure discovery,these evasive techniques will make differentiating between malicious and benign privacy disclosures difficult during privacy leak analysis. In this paper, we propose PrivacyContext to identify malicious privacy leak using context. PrivacyContext can be used to purify privacy leak detection results for automatic and easy interpretation by filtering benign privacy disclosures.Experiments show PrivacyContext can perform an effective and efficient static privacy disclosure analysis enhancement and identify malicious privacy leak with 92.73% true positive rate. Evaluation also indicates that to keep the accuracy of privacy disclosure classification, our proposed contexts are all necessary.

  • On Mapping of Address and Port using Translation (MAP-T)   Order a copy of this article
    by Aniruddha Bhattacharjya, Xiaofeng Zhong, Jing Wang, Xing Li 
    Abstract: Due to the shortage of IPv4 addresses, many hosts are currently assigned to a single IPv4 address by using one or a number of NAT devices. In these circumstances, an accessible public IPv4 address is consigned to the NAT device. The 6to4 tunnel endpoint must be executed with that specified NAT device. However, numerous NAT devices are already positioned and cannot be upgraded for executing 6to4 due to technical and/or economic reasons. Solutions depending on Double Network Address Translation 64 are a good way to utilize shared IP4 addressing. In addition, it allows the network operator to optimize his or her work and operations around the IP6 network. Mapping of address and port using translation (MAP-T) is a technique that accomplishes double translation on Border Relay (BR) and customer edge (CE) devices. IPv4 and IPv6 forwarding, IPv4 and IPv6 fragmentation functions, and NAT64 translation functions are used by MAP-T. This enables increasing numbers of IPv6 in both clients and servers in order to possess the best defence against certain attacks, such as routing loop attacks, spoofing attacks, denial-of-service attacks, etc. It is necessary to first evaluate hardware/software support with application porting, as well as limit the scope and interaction mechanisms. We have here proposed some procedures for creating frameworks and sustaining secure IPv6 networks. According to applications, environs and architecture, it is possible to achieve stable and secure IP6 networks.

    by Rakesh Ahuja, Sarabjeet Singh Bedi 
    Abstract: An MPEG-2 based robust, invisible and blind watermarking scheme for video is presented. The proposed algorithm using the DC coefficients from 8 x 8 block of discrete coefficient transforms matrices generated from candidate IDR frames picking periodically in order to embed the scrambled binary watermark. The watermark can only be extracted by using the secret keys, which also enhances the security of watermark itself. Therefore the extraction will never possible without knowing the actual keys. The robustness is evaluated by testing against image processing attacks and video processing intentional and non-intentional attacks by evaluating two parameters as Normalized Correlation and Bit error Rate in order to find the degree of similarity and degree of dissimilarity respectively between the original and extracted watermark. The superiority of the proposed video watermarking algorithm is that the excellent robustness achieved to common video processing unintentional attacks as synchronization attacks and MPEG-2 compression attack by comparing it previous work and also good perceptibility obtained without changing the motion vectors during the DPCM process of MPEG-2 encoding scheme

  • HYBRID RSA based highly efficient, reliable and strong personal Full Mesh Networked messaging scheme   Order a copy of this article
    by Aniruddha Bhattacharjya, Xiaofeng Zhong, Jing Wang, Xing Li 
    Abstract: Efficient balancing of privacy, and strong authentication in end-to-end (E2E) security constitutes a challenging task in the field of personal messaging. Since RSA is a ubiquitous approach, we here propose a hybrid RSA-based, highly efficient, reliable, and strong personal full mesh networked messaging scheme. M-Prime RSA and CRT-RSA with shared RSA makes our Hybrid RSA decryption much more secure and efficient, and protects our users with complete privacy. However, computational modular exponentiation complexity and partial key exposure vulnerability of RSA present two major obstacles. Low modular complexity and asymptotic very slow speed of decryption of RSA, with the ease and speed problem in encryption of RSA are also problems to be solved. Our Hybrid RSA cipher resolves all of the above issues, and provides protection against exploitation of multiplicative property and homomorphic property of RSA. Our full mesh networking scheme also ensures E2E encryption for all peers. So, our three-way authenticated Hybrid RSA messaging scheme achieves a perfect balance of efficiency, security, authentication, reliability, and privacy. Consequently, our scheme offers a smarter choice for private messaging in existing, as well as future, Internet architectures.

  • Study on Data Fuzzy Breakpoint Detection in Massive Dynamic Data flow
    by yingying mao, hao yuan 
    Abstract: The current method obtains the frequency of occurrence of abnormal data detected in the adjacent regions through reading between the sensor and the adjacent conversion data, and uses the frequency of occurrence of abnormal data to describe the spatial correlation, according to readings of sensor data using the Bayesian analysis method of sensor to determine whether the sensor is abnormal. But this method has the problem of low detection accuracy. For this reason, this paper proposes a method to detect the fuzzy breakpoint of data in the massive dynamic data flow. Firstly, this method used the amplitude difference method to determine the abnormal data amplitude and the discrete point difference of data fuzzy breakpoint, and then used the wavelet transform to extract the features of inflection point of the data fuzzy breakpoint. Combined with the features of inflection point of the extracted data fuzzy breakpoint, we carried out the support vector machine classification, and detected the data fuzzy breakpoints in the massive dynamic data flow. Experimental results show that the proposed method can effectively improve the accuracy of fuzzy breakpoint detection.

  • SAPMS: A Secure and Anonymous Parking Management System for Autonomous Vehicles
    by Oladayo Olakanmi 
    Abstract: Recent surveys on Autonomous Vehicle (AV) (SAE level 5) have shown its potential in transforming road transportation system by not only making roads safer, but enhances car sharing and mobility. Although, its advent will revolutionize road transportation, but before this could be achieved vital operations in road transportation management systems will need to be modified or redesigned. One of these operations is parking system; most of the existing parking system are targeted towards non-autonomous vehicles (level-0 vehicles) where parking is not only distance-bound but parking prices are affected by other factors such as time and location. In this paper we propose a smart and anonymous parking management system using a novel space selection technique and anonymous authentication for space selection and reservation. The parking system is capable of anonymous-search for different parking spaces, and optimally determines whether to perform time-piece parking or single parking based on parking cost. To achieve this, the system determines the parking pattern with the lowest parking cost using the developed space selection algorithm and anonymous authentication scheme. The performance of the system was evaluated in terms of estimated computation cost and possibility of obtaining optimal parking pattern under the dynamic pricing system. The results showed that the proposed system is capable of selecting the best parking pattern in terms of cost. The results of the authentication overhead analysis show the estimated anonymous authentication time of 29:08ms for the propose scheme as against 51.9ms and 48.30ms of the two state-of-the-art anonymous schemes proposed in [32] and [27] respectively.

  • Novel Implementation of Defense Strategy of Relay Attack based on Cloud in RFID systems   Order a copy of this article
    by He Xu 
    Abstract: Radio Frequency Identification technology (RFID) is widely used in identity authentication and payment, and it also becomes an indispensable part of daily life. Cloud based RFID systems have broad application prospects, and can be provided as a service provided to individuals or organizations.For example, RFID cards can be used for cash-less payment, physical access control, temporary rights and identification in cloud environment. When an RFID card is used, there is a wireless transaction between the card and its reader, which could be attacked by several methods, including a relay attack. Relay attacks are difficult to completely prevent and a serious threat to RFID systems security. An attacker could use limited resources to build up this kind of attack and may need little knowledge of the underlying protocol. In recent years, researchers have proposed solutions using second channels to resist relay attack, such as using environmental measurements including noise, light and temperature. This paper describes research on the defense techniques for relay attacks in Cloud based RFID systems.The Cloud based Architecture for RFID systems typically consists of RFID tags, card readers (fixed or mobile) and Cloud-based server functionality.

    Abstract: Public key encryption with keyword search(PEKS) enables one to retrievernencrypted data stored on an untrusted server without revealing the contents. Now,beyond single keyword search, more and more attention have already been paid to the problem of multi-keyword search. However, existing schemes are mainly based on composite-order bilinear groups. In this paper, we propose a public key encryption with conjunctive and disjunctive keyword search(PECDK) scheme which can simultaneously support conjunction and disjunction within each keyword field for cloud storage. It is based on prime-order bilinear groups, and can be proved fully secure under the standard model.

    Abstract: Cloud computing is a product of computer technologies combined with network technologies and it has been widely applied in China. Experts and scholars in all fields begin to make many studies of cloud computing infrastructure construction and effective resource utilization. With the improvement of cloud computing technology (especially security technology), Internet finance will be deployed widely and will develop rapidly. ITFIN (Internet finance) is the results of finance comprehensively combined with network technology. It is also a new ecological finance fermenting in this Internet era. ITFIN integrates online transaction data generated in various social network. It studies and judges the credit standing of customers and completes credit consumption, loan and other borrowing behavior by e-payment. With ITFIN, people can enjoy financial services in dealing with various problems. However, one person can play many identities in the network. This phenomenon posed a severe challenge to ITFIN network security and has largely intensified the risks, including the operational risk, market selection risk and network and information security risk. ITFIN resolves the risks by establishing a reliable, reasonable and effective risk assessment model. We conducted theoretical and empirical analysis, then constructed an assessment model against Chinas ITFIN risk. The model integrates rough set and PSO-SVM (particle swarm optimization support vector machine). Finally, the model was used to assessment the ITFIN risk in China. The empirical research results indicate that the model can effectively reduce redundant data information with rough set theory. The theory also guarantee a reliable, reasonable and scientific model, enhance the classification effect of the model. The parameters of SVM model obtained by optimizing with PSO can effectively avoid local optimum, improve the effect of the classification model. Overall, the model has good generalization ability and learning ability.

    by Lei Chen, Jing Zhang, Lijun Cai 
    Abstract: Map-Reduce scheduling in the heterogeneous datacenter has been aroused more and more attention, and faces some new challenges on energy consumption, execution time, and job cost. To further balance the performance of job secluding among job cost, execution time and energy consumption, a locality-aware and energy-aware Map-Reduce multiple jobs scheduling algorithm is proposed for the heterogeneous datacenter in this paper. Firstly, the importance of rack in data locality and energy saving is analyzed. Secondly, a capacity pre-judged method is developed to measure the ideal capacity of one rack for different jobs, where energy-efficient is defined to measure the balance status of rack usage among job cost, execution time and energy consumption in the job scheduling process. Thirdly, based on pre-judged idea best capacity of racks, multiple jobs pre-assignment method is proposed to adjust the job execution order for improving the resource utilization and avoiding the resource waste from the traditional first-come-first-served scheduling model. By using multiple jobs pre-assignment method, each job is centrally assigned to virtual machines of several booked racks for saving energy consumption and reducing data communication. Finally, after job pre-assignment stage, all tasks of one job are split into many task groups where multiple Map tasks and one reduce task are merged into a task group and pasted a same label. Further, a parallel task execution strategy is used to ensure each virtual calculate all tasks of multiple task groups for enhancing data locality and decreasing data communication. By comparing with other three algorithms, the extensive experimental results show our algorithm has good performance on job execution time, cross rack traffic, and energy consumption in the heterogeneous datacenter.

    by Xiao Zhang, Shengli Liu, Shuai Han 
    Abstract: Proofs of Retrievability (PoR) enables clients to outsource huge amount of data to cloud servers, and provides an efficient audit protocol, which can be employed to check that all the data is being maintained properly and can be retrieved from the server. In this paper, we present a generic construction of PoR from Linearly Homomorphic Structure-Preserving Signature (LHSPS), which makes public verification possible. Authenticity and Retrievability of our PoR scheme are guaranteed by the unforgeability of LHSPS. We further extend our result to Dynamic PoR, which supports dynamic update of outsourced data. Our construction is free of complicated data structures like Merkle hash tree. With an instantiation of a recent LHSPS scheme proposed by Kiltz and Wee (EuroCrypt15), we derive a publicly verifiable (dynamic) PoR scheme. The security is based on standard assumptions and proved in the standard model.

  • A Robust Reversible Image Watermarking Scheme in DCT domain using Arnold Scrambling and Histogram Modification   Order a copy of this article
    by Soumitra Roy, Arup Kumar Pal 
    Abstract: Among the various watermarking scheme, reversible watermarking scheme has drawn extensive attention in the recent years for its application in sensitive issues like medical, military and typical law-enforcement images. Cover image dependent embedding capacity and lack of robustness are the most crucial concerns of the reversible watermarking methods. To overcome these issues, a DCT(Discrete Cosine Transform) and histogram shifting based robust reversible image watermarking scheme using Arnold scrambling is presented in this paper. Initially, the image is decomposed into non-overlapping blocks. In the next step, DCT is employed on each block to embed a binary bit of watermark into each transformed block by modifying one pair of middle significant AC coefficients and subsequently there location map is generated for cover image restoration purpose. Then, this location map is embedded in the cover image using histogram modification technique. In the extracting side, at first location map is generated from image using histogram modification method. Then watermark is recovered from the image and using location map reversible image is reversed. The proposed reversible watermarking scheme has also been experimented to verify the robustness property against several image processing attacks and satisfactory results are achieved.

    by Sujarani Rajendran, Manivannan Doraipandian 
    Abstract: In recent technology development, images are playing vital role in different applications such as social network, biometrics, medical, military and satellite fields. It is essential to protect these image from intruders during transmission on insecure networks. This paper propose a new chaotic map for image cryptosystem by combining tent map and 2D logistic map in different form. The proposed 2D Logistic-Tent map (2DLT) generates two chaotic series. These chaotic series are used to perform the confusion and diffusion phases of image cryptosystem. A comparison between existing standard 2D logistic map and proposed 2D logistic-tent map shows that the proposed map has high random chaotic series than the existing one. In order to evaluate the strength of the proposed image cryptosystem, the developed chaos cryptosystem was subjected to different analysis such as differential, key size and sensitivity, chosen plain text and cipher text attack analyses. All the analysed results proved that the proposed cipher has good security level and can be used for different secure image communication applications.

  • A New Statistical Attack Resilient Steganography Scheme for Hiding Messages in Audio Files   Order a copy of this article
    by Dulal Kar, Anusha Nakka, Ajay Katangur 
    Abstract: Attacks against steganography, particularly the ones based on statistical analysis are found to be useful in many situations that use images to hide secret messages in them. Similar attacks are also possible for audio steganography to detect presence of a hidden message in an audio. In this work, we present a novel scheme for audio steganography that preserves first-order statistical properties of the cover audio after embedding a secret message in it to avoid detection by automated tools. Particularly, the scheme preserves the frequency distribution of audio samples in the resultant audio in relation to the cover audio, i.e., the histogram of the resultant audio obtained after embedding a secret message is the same as the one of the original cover audio. As a result, the scheme can avoid detection by any histogram based or similar statistical attacks. There exist similar histogram preserving techniques for image steganography, however, they are not readily suitable for audio steganography as human auditory system is highly sensitive to detect or discriminate subtle changes in an audio. Accordingly, in this work, we present a new scheme that can achieve higher capacity, and at the same time, is more effective to avoid detection by human auditory system. Particularly, the scheme allows a way to maintain a desired level of signal-to-noise ratio in the resultant stego audio while embedding a secret message. The scheme applies a technique of partitioning the audio samples in the cover audio, which is followed by a technique of rearranging or reordering of the audio samples in each partition through an encoding process for embedding the secret message bits in it. Partitioning of samples in the audio is governed by a specified error limit on each individual sample. We show how this error limit can be determined from a signal-to-noise ratio that should be maintained in the stego audio to avoid detection.

  • Robust Injection Point-Based Framework for Modern Applications against XSS Vulnerabilities in Online Social Networks (OSNs)   Order a copy of this article
    by Shashank Gupta, Brij Gupta 
    Abstract: Scripting languages like JavaScript has been extensively utilized for enhancing the usability and interactivity of modern applications. However, this has also resulted in the occurrence of numerous vulnerabilities, including Cross-Site Scripting (XSS) attacks in online social networks (OSNs). This attack is generally occurred due to inability of data in sanitizing user-supplied values injected at possible injection points of web pages. In this paper, we introduce a universal and an automated server-side flexible framework, XSS-Explorer, which automatically scrutinizes the web applications in OSNs in order to discover XSS attack vectors. XSS-Explorer is capable enough for exploring and recognizing all the injection points of web application and produces explicit XSS attack injection investigations for all such injection points. Our approach is based on methods permitting precise filling of injection points of forms with usable info. The identification of such injection points permits our technique to retrieve each possible web page of application, allowing a wider exploration and accelerating the discovery frequency of XSS attack vectors. We evaluate efficiency of our scheme on a suite of three tested open source applications by applying F-test Hypothesis and F-Measure. These evaluations indorse that precise filling of the injection points by only usable firms an enhanced efficiency of the tests, thus accelerating the recognition rate of XSS attacks on large data.

    by Yujuan Sun 
    Abstract: The three-dimensional reconstruction from single input image is quite difficult due to many unknown parameters, such as the light condtions, the surface normal and albedo of the object. However, there are overall similar characteristics for different human faces, such as the shapes and the positions of the eyes, nose, mouth and ears are generally identical. The similar characteristics has been used in this paper to relax the numbers of the input face images, and reconstruct the 3D shape based on a couple statistical model. Moreover, the light condition of the single input image can be different from that of training database. The experiment results show the effectiveness of the proposed method.

  • Node Authentication Algorithm for Securing Static Wireless Sensor Networks from Node Clone Attack   Order a copy of this article
    by Vandana Mohindru, Yashwant Singh 
    Abstract: Wireless Sensor Networks (WSN) consist of small size sensor nodes with limited sensing, processing, communication, and storage capabilities. These sensor nodes are vulnerable to the node clone attack where the attacker compromises the node and extracts secret information from the node and replicate the large numbers of clones of captured node throughout the sensor network. Therefore, providing security in such networks is of utmost importance. The main challenge to achieve this is to make the security solution energy efficient so that it is feasible to implement in such resource constrained nodes in WSN. In this paper, an energy efficient algorithm is proposed for node authentication. Aim of node authentication algorithm is to authenticate the sensor nodes before message communication within WSN so that cloned nodes are identified in the initial step of the communication. This algorithm uses encryption decryption operations and also XOR, extraction, bitwise shift operations. The performance of the proposed algorithm is analyzed in terms of communication, storage, and computation overheads metrics. Finally, performance of the proposed algorithm is analyzed with the other node authentication algorithms.

    by Amita , Amandeep Kaur, Marut Kumar 
    Abstract: Due to advancement in communication technology, data are transmitted over the network which is either confidential or private. So, the information security is one of the most critical factors considered when secret data is transmitted between two parties. Another important issue is the bandwidth utilization for data transmission. Image steganography is a widely used technique for data hiding. It is used in critical applications like military and medical areas. Most of the work is done in uncompressed images, which leads to high storage and large bandwidth required for transmission. Keeping these two factors in mind, this paper presents the multilevel histogram shifting technique in the compressed domain with the addition of adaptive block division scheme to improve the embedding capacity as well as reduce the utilization of the bandwidth. In this method, Absolute Moment Block Truncation Coding (AMBTC) Compression technique has been used for compression because of its good compression ratio.

  • Improved Pixel Relevance based on Mahalanobis Distance for Image Segmentation   Order a copy of this article
    by Lihua Song 
    Abstract: Image segmentation is to partition one given image into different regions. In essence, the procedure of image segmentation is to cluster the pixels into different groups according to the retrieved features. However, artifacts in the given images make the features be contaminated, resulting in poor performance of current segmentation algorithms. Therefore, how to reduce the effect of image artifacts is one hot topic in image processing. In current algorithms, neighbor information is adopted to resist the effect of image artifacts. However, when the image is contaminated with high-level noise, current algorithms also perform poor. Recently, non-local information is introduced to improve the quality of segmentation results, in which pixel relevance between pixels is crucial. In this paper, pixel relevance is measured based on Mahalanobis distance. More specifically, we consider the distribution of different samples and relevance interference between samples in the procedure of computing pixel relevance.Then, a new algorithm based on the novel pixel relevance is proposed, where non-local information can be incorporated into fuzzy clustering for image segmentation. The new algorithm can improve the robustness of corresponding algorithms greatly. Experiments on different noisy images show that the proposed algorithm can retrieve better results than conventional algorithms.

    by Rohit Raja, Tilendra Shishir Sinha, Raj Kumar Patra, Shrikant Tiwari 
    Abstract: In the recent times, it has been found from the literature that, only front-view of human-face images are used for the authentication of the human being. Very little amount of work has been carried out using side-view and temporal-view of the human-face for the authentication of the human being. The main fact lies in the mentality of present youth, who are very busy in taking the photographs with different poses. Generally the poses are taken from side-view. Hence in the present paper, the main focus has been kept, in the authentication process using methods of recent trends in the field of engineering. The main objective is to handle the variability in human-face appearances due to changes in the viewing direction. Poses, illumination conditions, and expressions are considered as three main parameters, which are processed for the overall authentication process. For the overall processing, extensive feature set like texture, contrast, correlation and shape are extracted by employing modified region growing algorithm and texture feature by Local Gabor XOR Pattern (LGXP) and Artificial Neural Network (ANN) technique. The present work has been analysed using the data of different subjects with varying ages.

  • Nested Context-Aware Sanitization and Feature Injection in Clustered Templates of JavaScript Worms on the Cloud-Based OSN
    by Shashank Gupta, Brij Gupta, Pooja Chaudhary 
    Abstract: This article presents an enhanced JavaScript feature-injection based framework that obstructs the execution of Cross-Site Scripting (XSS) worms from the virtual machines of cloud-based Online Social Network (OSN). It calculates the features of clustered-sanitized compressed templates of JavaScript attack vectors embedded in the HTTP response messages and inject them on the OSN server in the form of comment statements in such code. It further re-executes the feature calculation procedure of JavaScript code on the generation of HTTP response in online phase. Our framework detects the injection of XSS worms by comparing the values of these two injected feature sets. Any variation observed in such JavaScript feature set indicates the injection of XSS worms on the cloud-based OSN server. The injected worms will further undergo through the process of nested context-aware sanitization for its safe interpretation on the web browser. The prototype of our framework was developed in Java and installed in the virtual machines of cloud environment. The experimental evaluation of our framework was performed on the platform of OSN-based web applications deployed in the cloud platform. The performance analysis done (using F-Score and F-test) revealed that our framework detects the injection of malicious JavaScript code with low false negative rate and acceptable performance overhead. The novelty of our cloud-based framework lies in the fact that it optimizes the JavaScript feature calculation procedure by executing it on clustered templates of JavaScript attack payloads, unless its execution on redundant injected JavaScript code adopted by the existing state-of-art.

    by Manikandasaran S S, Arockiam L, Sheba Kezia Malarchelvi P.D 
    Abstract: Data management is a monotonous task for Small and Medium Scale Enterprises (SMEs). Cloud storage provides enormous virtual storage space to store the cloud users data. Data outsourcing helps the SMEs to reduce headache to manage the data in their premises. Many SMEs are attracted to outsource their data to the cloud. Once the data are outsourced, they are kept by the third party cloud storage providers and it should be controlled and monitored by them. The users dont have the rights to control and monitor their own data in the cloud storage. This causes the data security issue of outsourced data in cloud storage. If anything wrong happens on the data, the users suspect the cloud storage providers. Ensuring the confidentiality of outsourced data plays a vital role in the cloud security. To ensure the confidentiality of outsourced data, this paper proposes a technique called MONcrypt. MONcrypt is based on obfuscation technique. Obfuscation is a process of masking the original text into irrelevant text without using any key unlike encryption. MONcrypt uses key for de-obfuscation. This novel obfuscation technique is used to ensure the confidentiality of outsourced data in cloud storage. The paper compares the proposed technique with existing technique like Base32, Base64, Hexadecimal Encoding, DES, 3DES and Blowfish. The proposed technique shows better performance and security compared with the existing techniques.

  • A Robust and Blind Image Watermarking Scheme in DCT Domain   Order a copy of this article
    by Arup Kumar Pal, Soumitra Roy 
    Abstract: In this paper, the authors have presented a robust and blind watermarking scheme based on Discrete Cosine Transform (DCT) for protecting the copyright ownership of digital images. Initially, the image is decomposed into non overlapping blocks and subsequently DCT is employed on each block. In this work, a binary bit of watermark is embedded into each transformed block by modifying some middle significant AC coefficients using repetition code. During the embedding phase of the proposed method, DC and some higher AC coefficients are kept intact after zigzag scanning of each DCT block to ensure the high visual quality of watermarked image. The proposed scheme is suitable to protect the copyright information even in compressed form of the watermarked image since the scheme exploits the middle bands of DCT coefficients for embedding the watermark bits and in general high frequency bands are filtered in the compression process. The proposed scheme is tested on standard images and the simulation results show that the proposed watermark embedding procedure does not reflect too much impact on the visual quality of watermarked images. The proposed scheme is also tested to verify the withstand capability against several image processing attacks like image enhancement, image noising, cropping operation, sharpening, JPEG compression, geometric operation like image rotation etc. and satisfactory results are achieved.

    Abstract: Phishing is one of the major problems faced by the cyber-world and could lead to financial losses for both industries and individuals. In this paper, we present our proposed system which can detect Phishing attacks in financial and e-banking websites using link and visual similarity relation. Our proposed system analyse the keywords, hyperlinks and CSS layout of webpage, as many links point to corresponding legitimate page and phisher always tries to mimic the visual design of the page to steal confidential information. In the proposed system, we make set of all the associate domains and explore the links and similarity relation. In addition, we use the login form and whitelist based filtering to increase the running time and reduce the false positive rate. Our proposed system is not only able to detect phishing page accurately but its source page. Moreover, it does not require any prior training to detect zero-hour phishing attacks. Experiments are conducted over a 6616 phishing and legitimate sites and proposed system gives approximately 99.72% true positive rate and less than 1.89% false positive rate.
