Research ArticleOpen accessIn the author namesHybrid Broadcast Group Management Protocol for Secure, Scalable and Efficient Group CommunicationM. Sayee Kumar, T. PurusothamanIn hasty growth of communication, security plays a central role in maintaining confidentiality of data in group communication. Keeping the data intended for the group in confidential manner is the most important security feature need to be sustained for the group communication. An efficient group key management mechanism named as Hybrid Broadcast Group Management Protocol (HBGMP) is devised based on … …Journal of Computer Science, Vol. 11, Issue 2 · 17 Sep 2014 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the author namesOPTIMIZING BATCH REKEYING INTERVAL FOR SECURE GROUP COMMUNICATION BASED ON QUEUING MODELA. Vasanthi, T. PurusothamanRapid growth of Internet spawns many group oriented multicast applications like Internet pay TV, news dissemination and stock quote system. The fortes of these applications are the support of dynamic, scalable group membership and group members are geographically divergent. As members of the group move in and out, an imperative cryptographic rekeying model should be applied to preserve the confidentiality … …Journal of Computer Science, Vol. 10, Issue 2 · 20 Nov 2013 · 6,456 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Enhanced and Cost Effective Group Key Management Scheme for Multicast NetworkSaravana Kumar Muthusamy, Purusothaman Thiyagarajan, Lavanya SelvarajKey management plays a vital role in the data communications. The proposed scheme is a key management scheme that provides more efficient and secure methods for key generation and utilization. Enhanced and cost effective key management scheme achieves a secure communication between the members within the group-based network. In this scheme, the group key is generated only once which is … …Journal of Computer Science, Vol. 9, Issue 4 · 10 May 2013 · 6,390 accessesView PDFCite
Research ArticleOpen accessIn the author namesExplicit Allocation Strategy with Deadline and Budget Constraint Algorithm in Bag of Tasks GridM. Suresh Kumar, T. PurusothamanProblem statement: This study is for effective scheduling of grid jobs based on economy for space shared resources in Bag of tasks grid. Grid Computing aims in combining the power of heterogeneous, geographically distributed, multi-domain computational resources to provide high performance or high throughput. Approach: Space shared resources are parallel supercomputers and clusters of workstations that provides a great amount … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 6,229 accessesView PDFCite
Research ArticleOpen accessIn the author namesEfficient Star Topology based Multicast Key Management AlgorithmK. Saravanan, T. PurusothamanProblem statement: Secure group communication is very important for many applications such as internet pay sites. It provides efficient delivery of identical data to only the customers in the group. In large and dynamic multicast groups, the group keys of members have to be changed frequently whenever the member leaves or joins. A common method is to apply a symmetric … …Journal of Computer Science, Vol. 8, Issue 6 · 22 Mar 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the author namesPerformance of Improved Directed Diffusion Protocol for Sensor Networks under Different Mobility ModelsK. E. Kannammal, T. PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,749 accessesView PDFCite
