  • A security enhanced user authentication scheme for multi-server environment without using smart cards   Order a copy of this article
    by Pengshuai Qiao 
    Abstract: With the popularity of Internet and wireless networks, more and more network architectures are used in multi-server environment, in which users remotely access servers through open networks. For the reliability of accessing these remote services, user must pass a verification procedure to obtain the authorization for legal resource acquisition and data exchange. In 2008, Lee et al. proposed an authentication scheme for multi-server architecture. Recently, Yeh et al. demonstrated that Lee et al.s scheme is insecure against server spoofing attack, user impersonation attack and undetectable online password guessing attacks. Yeh et al. also proposed an improved authentication scheme and claimed their scheme could withstand various attacks. Unfortunately, we find that Yeh et al.s scheme is still vulnerable to offline password guessing attack and stolen-verifier attack. Furthermore, a security enhanced authentication scheme is developed to eliminate the identified weaknesses.

  • Hybrid Secure GSM Architecture using DNA Computing based Hyperelliptic Curve Cryptography   Order a copy of this article
    by Vijayakumar Perumal 
    Abstract: Wireless Mobile Communication has become more familiar and popular among other communication system for transmitting data to enable the user to communicate with other third parties at any place at any time. Due to third party interception, transmission of data, connection establishment, connection release, billing processes are in insecure environments. So many researchers had put their effort to develop an innovative authentication scheme for GSM network. The existing authentication scheme provides security with high communication and computational overhead using a symmetric key cryptography. The proposed scheme mainly focuses on providing security to Global System for Mobile communication system using Hyperelliptic Curve Cryptography and DNA computing technique for Mutual Authentication, Secret key generation and, data encryption and decryption algorithm. Finally a security analysis shows that authentication algorithm is more secure and efficient.

  • Preserving the Confidentiality of Digital Images Using a Chaotic Encryption Scheme   Order a copy of this article
    by Alireza Jolfaei, Ahmadreza Matinfar, Abdolrasoul Mirghadri 
    Abstract: Confidentiality of digital images is an important requirement for many multimedia applications and services. To maintain confidentiality, encryption of digital images is essential. Digital images are usually very large and encrypting such bulky data induces many performance overheads, which can be too expensive for real-time applications in resource constrained environments. In this paper, we propose a chaotic image encryption scheme which satisfies the need for both lightweightedness and security. To justify the security and efficiency, the new cipher was evaluated using a series of statistical tests. These tests included visual testing and histogram analysis, randomness analysis, correlation analysis, entropy analysis and image encryption quality analysis. Based on all analyses and experimental results, it is concluded that the proposed scheme is effective, efficient and trustworthy to be adopted for image encryption.

  • Real-time digital forensic triaging for cloud data analysis using MapReduce on Hadoop framework   Order a copy of this article
    by Digambar Povar, Saibharath , G. Geethakumari 
    Abstract: Cloud computing is a relatively new model in the computing world after several computing paradigms like personal, ubiquitous, grid, mobile, and utility computing. Cloud computing is synonymous with virtualization which is about creating virtual versions of the hardware platform, the Operating System or the storage devices. Virtualization is omnipresent in the cloud environment that poses challenges to implementation of security as well as cybercrime investigation. Techniques used in traditional digital forensics may not be appropriate for timely analysis of large capacity virtual machine hard disk file or virtual storage of a cloud user. Hence, there is a need for reducing analysis time for cloud crime cases like child pornography, murder, hacking, death threats, missing persons, drugs activity, financial frauds etc. In this paper we designed and developed a new Real-time digital forensic analysis process that will minimize the overall processing time of evidence using parallel programming model (MapReduce) on a distributed computing platform Hadoop. The approach we designed would answer the queries of Investigator in real time by searching user specified patterns in given evidence by distributing parts of evidence to clusters of commodity machines with local store and processing them in parallel. This approach can also be used for indexing search patterns (for example - headers and footers of files) to carve files from evidence data.

  • Assessment of uniformity of byte distribution in a file based on the wavelet transform as an approach to search encrypted data   Order a copy of this article
    by Vesta Matveeva 
    Abstract: This article is focused on the search of the encrypted data in the file system, which is an important step in digital forensics. Encryption is widely used today, among others by malefactors to conceal data, suggesting that encrypted information can be hidden in the file system. There are means of detection of encrypted files, but they have significant limitations and may not be used for the free space of the file system. Statistical tests can also be used for this purpose but they are resource and time consuming. Therefore, the article proposes a new approach to searching for encrypted data, based on the assessment of uniformity of data, with the ability to localize the heterogeneity, which reduces type I error to zero. This approach has its drawbacks, in the form of type II errors; however it can be improved by manipulating parameters that are used for assessment of uniformity.

  • A post-quantum communication secure identity-based proxy-signcryption scheme   Order a copy of this article
    by Xiaojun Zhang, Chunxiang Xu, Chunhua Jin, Junwei Wen 
    Abstract: Proxy-signcryption is a variation of an ordinary signcryption scheme and has been used in many applications where the delegation of rights is quite common. In a proxy-signcryption scheme, an original signcrypter needs to delegate his signcryption capability to a proxy signcrypter to signcrypt messages on behalf of the original signcrypter. By combining the functionalities of proxy signature with identity-based signcryption, in this paper, we propose a novel identity-based proxy-signcryption (IBPSC) scheme from lattice assumptions in the random oracle model. Meanwhile, the security requirements of our IBPSC scheme have been analyzed, and our scheme can even resist quantum computer attacks. Compared with existing IBPSC schemes, our scheme is more secure and more efficient. To the best of our knowledge, there is still no relevant IBPSC scheme based on lattice, which is an interesting stepping stone in the post-quantum cryptographic communication.

  • Related-Key Cryptanalysis on 7-round AES-128/192   Order a copy of this article
    by Jie Cui, Hong Zhong, Jiankai Wang, Runhua Shi 
    Abstract: AES is the most widely used block cipher today, and its security is one of the most important issues in cryptanalysis. In this paper the authors present two attacks on 7-round AES-128/192 to improve the known cryptanalysis by changing the order of round transformations, using the alternative representation of the round keys, exploiting the relationship of keys, designing the key difference pattern properly. We reduce complexity to 2160 and 2104 respectively using the improved attack methods. Our attacks are faster than the best previous attacks.

  • Adaptation Of Frames For GOP Using NSEW Affine Translation For Effective Privacy Protection Mechanism   Order a copy of this article
    by D. Raveena Judie Dolly, Josemin Bala, J.Dinesh Peter 
    Abstract: The Group of Pictures (GOP) plays a very vital role in the privacy protection mechanism when data hiding is preferred through video transmission. GOP varies for every conventional video compression standards. The frame identification plays a key role in framing GOP. If frames are chosen adaptively using a matching criteria instead of precoded GOP the further processing for video compression could be effectively done. The quality of the reconstructed video after compression can be improved subjectively if GOP is selected properly and thus the embedded data can be retrieved without degradation. It is observed that B-frames in a GOP takes more computation time since it depends on the previous and next frame to be processed. So, NSEW affine translation technique is proposed to convert B-frames to either P-frames or I-frames depending on the matching criteria between frames. The result shows that the performance objective evaluation coincides with the subjective evaluation.

  • Recognition of Elephants in Infrared Images Using Clustering based Image Segmentation   Order a copy of this article
    by Siva Mangai 
    Abstract: Object recognition is a challenging task in image processing and computer vision. This paper proposes a clustering based image segmentation approach for elephant recognition. Appreciable recognition rate was achieved by k-means clustering technique followed by feature extraction and K nearest neighbour (K-NN) classifier. The k-means clustering algorithm employs the concept of fitness and belongingness to provide a more adaptive and better clustering process as compared to several conventional algorithms. Elephant shape features are extracted for the recognition. Recognition rate for each class is calculated for performance evaluation. Recognition rate for different K values in K-NN classifier is calculated to find a proper K value for the proposed design.

    Abstract: In mobile adhoc network, all the nodes will act as client/server and it has the capability to forward the packets. Security is major concern in wireless network due to decentralized topology. Intruders may attack the transmission path between source and destination. Existing technique used Adhoc On Demand Vector (AODV) routing protocol to detect the attackers by on demand basis. But it is not sufficient to detect all the denial of service attack. So proposed the new protocol as On Demand Attack Detection (ODAD) protocol is designed to detect various attacks in a different ways. It contains three modes to detect the various attacks. They are i. FDN (Finding Drop Node), ii. ACK (Acknowledgment) and iii. SNC (Self Node Correction). These modes are used to detect the attackers inside the mobile adhoc network and then inform about the intruders to remaining node in the network. Experimental results analyze the performance of throughput, packet delivery rate, drop rate and delay. This technique decrease the delay and drop rate, and increase the delivery rate and throughput compared with the existing technique.

    by P. P. Joby, P Sengottuvelan 
    Abstract: Wireless Sensor networks (WSN) is an embryonic communication technique in the universe to be engaged for precarious circumstances resembling battle arenas and viable applications such as construction, transportation surveillance, territory monitoring, clever homes etc. Currently wireless sensor network facing a foremost problem is result from security issues. There are many security methodologies were available for wireless sensor network. Generally classified as two levels; one is low level, further categorized into privacy, key establishment, trusted network, secrecy, authentication, secure routing and etc. Another one is High level, further categorized into secure group management, Intrusion detection, data integrity and etc. This research Focusing on the network availability, prior revisions offered to protect the network beside denial of service attacks with the use of traffic monitoring proxies on some nodes. But if the governor nodes are miserable, then its vulnerable to network. To overcome this, the research put front a mechanism called election method to elect the control nodes in a clusters. To simulate this methodology, Packet tracer tool is used.
