Research ArticleOpen accessIn the abstractMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,732 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree TraversalP. Vidhya Saraswathi, M. VenkatesuluMany people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,699 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy Based Scheme for Combined Data Security in Mobile Ad hoc NetworksL. Kartheesn, S. K. SrivatsaProblem statement: In Mobile Ad hoc Networks (MANET) routing protocols, we require a network-level or link layer security. Since without appropriate security provisions, the MANETs is subjected to attacks like network traffic, replay transmissions, manipulate packet headers and redirect routing messages. In order to address these needs, a policy based network management system that provides the capability to express network … …Journal of Computer Science, Vol. 8, Issue 8 · 6 Aug 2012 · 6,725 accessesView PDFCite

KavithaProblem statement: Enterprises are migrating to the cloud environment at a faster pace. Security of information that is being processed by the applications and ultimately getting stored in the data centers are of big concerns of this newly evolving environment. The security of the data is a concern not only during transferring of data through the wires but also during … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 27 Jul 2012 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Anonymous Trust Based Routing Using Ant Colony OptimizationR. Kalpana, N. RengarajanProblem statement: Ad hoc networks are susceptible to malicious attacks through denial of services, traffic analysis and spoofing. The security of the ad hoc routing protocol depends upon encryption, authentication, anonymity and trust factors. End-to-end security of data is provided by encryption and authentication, topology information of the nodes can be obtained by studying traffic and routing data. This security … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 30 Jun 2012 · 6,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Mersenne Number Transform Diffusion Power AnalysisM. F. Al-Gailani, S. BoussaktaProblem statement: Due to significant developments in the processing power and parallel processing technologies, the existing encryption algorithms are increasingly susceptible to attacks, such as side-channel attacks, for example. Designing new encryption algorithms that work efficiently on different platforms and security levels to protect the transmitted data from any possible attacks is one of the most important issues in today’s … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractAuthenticated Broadcast in Heterogeneous Wireless Sensor Networks using Chinese Remainder Theorem AlgorithmKalyani Palanisamy, ChellappanProblem statement: The security in Wireless Sensor Networks (WSN) is a critical issue due to the inherent limitations of computational capacity, storage capacity and power usage.
