Research ArticleOpen accessAll words, across the recordSECRET HANDSHAKE ISSUE AND VALIDATE AUTHORITY BASED AUTHENTICATION SYSTEM FOR WIRELESS SENSOR NETWORKKamalanaban Ethala, R. Seshadri, N. G. Renganathan, M. S. SaravananWireless Sensor Networks (WSN) are major research area in the past few decades. WSN is formed by collection of sensor nodes. Power source life and memory size limit the hardware sources and these will decide the lifesapn of sensor nodes in WSN. Therefore, many resources based research issues are evolved in WSN. This study focused security issue and proposed authentication … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,429 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Proficient Traceback Approach Using Provincial Locality Aspects to Eliminate Denial of Service AttacksS. Periyasamy, K. DuraiswamyA Denial-of-Service (DoS) attack, a menace to the availability of resources and service to the intended user, is usually by augmenting the traffic in the communication medium. These attacks originate in either ways, internal or external to a network with the aim to suspend the legitimate user from getting his/her service. The DoS attacks have been countered through various approaches, … …Journal of Computer Science, Vol. 9, Issue 2 · 12 Apr 2013 · 6,026 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparing the Impact of Black Hole and Gray Hole Attacks in Mobile Adhoc NetworksUsha, BoseMobile Adhoc Networks (MANETs) are dynamic in nature. Any nodes can join and leave the network at any time. Hence any type of intruders can attack the communication at any time, especially the routing mechanism between the nodes. In this study, we study and understand two types of attacks which cause more damage to the routing performance of MANET; the … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Sep 2012 · 6,904 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Effective Contributory Re-Keying Approach to Compute Conference KeyD. Thilagavathy, M. RajaramProblem statement: With the explosive growth of and internet and web applications many emerging group-oriented distributed applications such as tele/video-conferencing, multiplayer games are based on group communication model that need security services such as privacy and data integrity Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,643 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMobile Ad Hoc Network Security for Reactive Routing Protocol with Node Reputation SchemeA. Suresh, Dr. K. DuraiswamyThe mobile node’s reputation in the Mobile Ad hoc Network (MANET) identifies its trust worthiness for secured multiple data communication. Unknown nature of the node’s communication status for initial period has great impact in the effective data transfer as MANET is self-organized and distributed. Problem statement: The functional operation of the mobile network relies on the trusty cooperation between the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,988 accessesView PDF Cite
