  • Efficient light-weight private auditing scheme for cloud-based wireless body area networks   Order a copy of this article
    by Xiaojun Zhang 
    Abstract: With the rapid development of cloud computing, cloud-based wireless body area networks (WBANs) provide powerful storage services, and process massive medical data efficiently. As the medical data are exploited to perform the clinical diagnosis and other special medical treatments, the integrity of the medical data stored in the cloud server is increasingly important. In this paper, based on the elliptic curve digital signature algorithm (ECDSA), we propose an efficient light-weight cloud storage private auditing scheme for medical data in WBANs. Our scheme enables a data owner to check the medical data integrity effectively personally, and does not need to retrieve the entire medical data set, thereby dramatically reducing the communication overhead. Moreover, we further extend our private auditing scheme to private batch auditing. Thus, the data owner can perform auditing task for multiple different medical data files simultaneously. The performance comparison demonstrates that our scheme is much more light-weight, and more practical in cloud-based wireless body area networks.

  • Monitor and Detect Suspicious Transactions with Database Forensics and Dempster-Shafer Theory of Evidence   Order a copy of this article
    by Harmeet Khanuja 
    Abstract: The digital investigators have now approached databases for investigating the cyber crimes. The illegal financial transactions on the web which goes undetected can now be revealed through database forensics. In response to this, we have proposed a methodology to detect the illegal financial transactions through database audit logs. The aim here is to monitor the database, detect the suspicious transactions and report the risk level of these transactions. Different databases are monitored to extract SQL transactions through their respective audit logs. The SQL transactions obtained are transformed and loaded in a standard XML format which contains financial records along with its metadata. Initially, we process the financial transaction records with Rule-Based outlier detection algorithm and classifies the transactions as per RBI rules. The suspected transactions obtained as outliers are marked with initial belief values. To verify the uncertainty of the suspected transactions we apply Dempster-Shafers theory of evidence which combines various evidence of suspected transactions obtained through audit logs. The experiments performed manifest the risk level of suspected transactions.

  • Robust, Imperceptible and Blind Video Steganography using RGB Secret, Maximum Likelihood Estimation and Fibonacci Encryption   Order a copy of this article
    by Barnali Gupta Banik, Abhinandan Banik 
    Abstract: According to the International Telecommunication Union, currently 51% of the world's population has Internet access; In developing countries, online video penetration has reached over 80% of total Internet usage. This implies that video sharing is very popular. Therefore, for secure confidential communication, secret data hiding in video can be a viable option to keep privacy. Hence in this article, a blind, key based technique of video steganography has been proposed in transform domain which can hide RGB image within a colour video. The novelty of this approach lies in the security imposed by various factors including scene change detection, pre-processing of secret image and the embedding technique. Here Maximum Likelihood Estimation has been applied as scene change detector to identify the video frame where the secret data embedding is taking place; For enhancing security, the secret image is scrambled by Fibonacci encryption before embedding. Lastly, Discrete Wavelet Transform based data hiding method has been implemented here which requires key for operation, can easily hide colour images without any perceivable differences and doesnt require cover video frame during extraction. Quality of the proposed method has been analysed by Peak Signal to Noise Ratio, Structural Similarity Index, Normalized Absolute Error and Correlation Coefficient; Robustness tests have been performed against various Steganalysis attacks namely Random Cropping, Rotating, Resizing and Histogram Equalization; At last, this method has been compared with the existing research works to demonstrate technological advancements.

  • Identifying Phishing Attacks in Communication Networks using URL Consistency Features   Order a copy of this article
    by Nureni Ayofe Azeez, Balikis Bolanle Salaudeen, Sanjay Misra, Robertas Damasevicius, Rytis Maskeliunas 
    Abstract: Phishing is a fraudulent attempt by cybercriminals, where the target audience is addressed by a text message, phone call or e-mail, requesting classified and sensi-tive information after presenting himself/herself as a legitimate agent. Successful phishing attack may result into financial loss and identity theft. Identifying foren-sic characteristics of phishing attack can help to detect the attack and its perpetua-tors and well as to enable defense against it. To shield internet users from phishing assaults, numerous anti-phishing models have been proposed. Currently employed techniques to handle these challenges are not sufficient and capable enough. We aim at identifying phishing sites in order to guard internet users from being vulnerable to any form of phishing attacks by verifying the conceptual and literal consistency between the Uniform Resource Locator (URL) and the web content. The implementation of the proposed PhishDetect method achieves an accuracy of 99.1%; indicating that it is effective in detecting various forms of phishing attacks.

    by Mustapha SADI, Mourad AMAD, Nadjib BADACHE 
    Abstract: Group key management is a challenge for securing group communications in the networks. This area is well studied in the literature. The strict characteristics of mobile Ad-Hoc networks makes the adaptation of classical existing solutions a real challenge. Elliptic Curves Cryptography (ECC) became the choice of encryption for wireless Ad-Hoc and sensor networks. It uses very small keys and is mathematically very effective, which makes them ideal in communication for small devices used today. Scalability is a basic factor that determines the e

  • Design and Implementation of a Ring Oscillator-Based Physically Unclonable Function on Field Programmable Gate Array to Enhance Electronic Security   Order a copy of this article
    by Massoud Masoumi 
    Abstract: Physically Unclonable Functions (PUFs) are functions that generate a set of random responses when stimulated by a set of pre-defined challenges. Since this challenge-response scheme extracts the secrets from complex physical properties of substrate material, such as the manufacturing variability of CMOS process and devices, they are called as physically unclonable or unpredictable functions. They are mostly used for hardware verification and/or device authentication mechanisms, access control, protection of sensitive intellectual property (IP) on devices and protection against insecure hardware connections and communications. PUF-based security approaches have numerous advantages compared to traditional cryptography-based techniques, including more robustness against physical and side channel attacks and suitability for lightweight devices such RFIDs.rnIn FPGA devices, PUFs are instantiated by exploiting the propagation delay differences of signals caused by manufacturing process variations. However, the real implementation of PUFs on FPGAs is a big challenge given the fact that the resources inside the FPGA is limited, and that it is not easy to simulate the behavior of PUF using the Xilinx software tools. In addition, many details about the implementation of PUFs is not given by the authors in related articles. In practice, it usually takes a long time to get a simple PUF to work both in simulations and on the board.rnIn this work, we describe a real implementation of ring-oscillator based PUF on Xilinx FPGAs and illustrate how such architecture is mapped into the FPGA fabric. Using this architecture, we obtained a unique 45-bit code which can be used to identify a chip between many similar devices of the same family in order to provide a strong access control and authentication mechanism. rn

    by Puneet Sharma, Deepak Arora, T. Sakthivel 
    Abstract: Mobile cloud alleviates the burden of mobile computing technology through a cyber - foraging methodology that bridges the resource-constrained mobile devices and resources-abundant cloud. Mobile cloud augments the mobile device capabilities that allow the access of social networking sites, online file storage, and Webmail from anywhere over the Internet by using the cloud. With the increasing popularity of Smartphones and cloud-based mobile applications, cybercriminals misuse the potential vulnerabilities to promote the criminal activities. Thus, the mobile cloud forensics has received a greater attention within the digital forensics community and the mobile devices have become a significant source for the forensic investigators to collect fruitful case-specific evidences. The rapid usage of Smartphones and technological advancements become a critical factor that creates significant challenges to forensic investigation process. Most notably, collecting the potential evidences from the mobile devices and cloud by applying forensically sound methods faces severe setback due to technological challenges. The rapid advancement of forensic investigation tools and methods are inevitable to cope up with the increasing criminal activities on the mobile cloud platform. To overcome these challenges, this study proposes a forensic process framework for mobile cloud applications that provide deep insights into the mobile cloud forensic process and identify the critical methods essential for forensic investigators. This is a preliminary study that presents a mobile cloud forensic process primarily consists of identification, collection and preservation, examination and analysis, and evidence correlation and presentation phases. Moreover, the proposed mobile cloud forensic process introduces examination and analysis of inter and intra-application on the mobile device and the evidence correlation phase between the mobile and cloud. The forensic examination and analysis phase targets to improve the evidence traceability in the cloud by determining the evidences related to the malicious activity of the suspected device in an efficient manner.

    by Kostantinos Kardaras, George Lambrou, Dimitrios Koutsouris 
    Abstract: In the present work we propose an Intelligence C3I concept by integrating public safety radio communication networks and DTV. Transparent operation is achieved through Internet Protocol (IP) interfaces. Terrestrial DTV will be used as an alternative Intelligence communications path that will be activated during major crisis and emergencies where system unavailability occurs. Decision support systems will take over to coordinate, command and control agencies in the public sector. The advantageous property of the proposed architecture is the autonomous, robust and reliable operation of the infrastructures regardless their operations in a stand-alone capacity or as integral part of a greater and transparent security/Intelligence network. The proposed network architecture can be used as a means to countermeasure against crisis (terrorist attacks, physical disasters etc.).

  • Risk Assessment of Smart Grids under Cyber-physical Attacks using Bayesian Networks   Order a copy of this article
    by Anas AlMajali, Yatin Wadhawan, Mahmood Saadeh, Laith Shalalfeh, Clifford Neuman 
    Abstract: Different technologies are used to manage the integration of smart devices with the conventional power grid. This new integration allows more control and monitoring capabilities for stakeholders and customers. However, it also makes the smart grid susceptible to new classes of cyber-physical threats that have to be analyzed, evaluated and mitigated. In this paper, we specifically evaluate the risk of manipulating circuit breakers that connect a power generator to the smart grid. Our main contribution is performing risk assessment of the grid by combining the vulnerabilities of its cyber domain and the transient stability analysis of its physical domain. First, we estimate the probability of compromising the Energy Control Center (ECC) using a Bayesian Network. The ECC can be exploited to manipulate circuit breakers. Second, we analyze the impact of manipulating circuit breakers in the IEEE 39-bus test system. Third, the probability of compromise and its impact are combined to quantify risk. Finally, we analyze the effect of integrating Photovoltaic (PV) systems on the stability of the smart grid under the same attack scenarios. The results indicate that integrating smart grids with PV systems can improve resilience even if a cyber-attack succeeds.

  • An Ontological Approach to Threats Pattern Collection and Classification: a preliminary study to Security Management   Order a copy of this article
    by O.T. Arogundade, T.E. Abioye, Sanjay Misra 
    Abstract: This study presents an agent based approach to resolve issues related to the collection and classification of software application anomalies and misuses with the aim of facilitating the reappraisal of security controls of information system (IS).The proposed system is assumed to be integrated with the existing IS in order to enhance information system security maintenance by continuously collecting identified threat behavior from the application intrusion detection system (IDS). The system comprises of several functional agents like the input collector agent, classifier agent, and tracking agent. The collector agent collects the identified threats by the IDS, the categorizer agent categorizes according to STRIDE model using pattern matching algorithm on the content of security knowledge base. The security knowledge repository is developed based on existing security ontology. The classifier classifies based on the threats IP address while the tracking agent collates all the threats profile. We presented the collect-categorize-classify-track (C3T) model. The potential usability of our work is demonstrated by a case study and its useful integration with further studies is also discussed.rn

  • Forward secure certificateless proxy multi-signature scheme   Order a copy of this article
    by Ronghai Gao 
    Abstract: In order to deal with key exposure problem, we introduce forward secure technique into certificateless proxy multisignature scheme, and give the formal definition and security model of forward secure certificateless proxy multisignature.Furthermore, we present a construction of forward secure certificateless proxy multi-signature scheme.Based on the difficulty of computational Diffie-Hellman problem, the proposed scheme is existentially unforgeable against adaptively chosen-message attacks and chosen- warrant attacks in the random oracle model. The proposed scheme does not use bilinear pairs in the key update and generation proxy signature phases, and updated proxy key is easy, thus it is more suitable for mobile environments. Our scheme has effectively dealt with the key exposure problem and certificate management problem.

  • Possible Attempts to Identify E-mail Header of the Sender for Academic Qualification Fraud   Order a copy of this article
    by Nathaporn Utakrit, Pongpisit Wuttidittachotti 
    Abstract: Education is the core of the countrys development. A good education can increase a persons chances of having a good job, consistent pay raises, and a stable life; without a degree, it will be more challenging to have these things. A diploma mill arises when a person without a degree wants to get a better job and earn a more substantial salary. Buying and selling degrees over e-mail is one way to avoid detection. This research aims to contribute to forensic counteractive measures that can identify and track the people who use e-mail for data sharing. This examination focused on senders e-mail that could be used as a part of juridical significance in criminal justice. This research had adopted e-mail forensic process to acquire, extract, analyse, and interpret data. The authors conducted the empirical analysis from the experimental e-mails headers using forensic tools and manual approach based on the Request for Comments (RFCs) as the primary guidelines. The scope excluded the analyses of e-mail contents and attachments. The study found that the commercial tool extracted headers less often than the free alternatives. All sending channels could identify the senders identification. E-mail sent from desktops provided the computer name and ISP of the sender. However, typical and anonymous e-mails can only trace back to the original mail servers. Although tools could provide investigators with ease and convenience, data acquisition and validation need to be done manually. Digital forensic experts must utilise their strong forensic analytical and investigative skills to formulate and present results and conclusions in a format that can be easily understood. This research is not the ad hoc mechanism, but it can be implemented in other criminal investigations or related endeavours.
