Research ArticleOpen accessIn the abstractOPTIMIZING 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 abstractEfficient 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 abstractRange Detection Multicast Routing Protocol for Mobile Ad-Hoc NetworksR. Velumani, K. DuraiswamyProblem statement: Many efforts have been implemented towards the Group membership management on multicast routing in MANETs, but the difficulties associated with Group membership management are still existed. Approach: Maintaining endurance of Group Leader (GL) in multicasting routing has been a great challenge to all the protocol having been invented so far. Results: This study provides the RDMP algorithm for … …Journal of Computer Science, Vol. 8, Issue 4 · 10 Feb 2012 · 6,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch of Modular Object Oriented Dynamic Learning Environment E-Learning on Social Study for Elementary School StudentsTian-Syung Lan, Shu-Chun ChiuProblem statement: As the progress of digital technology, involving e-learning into curriculum becomes a novel trend. In general, the teaching practice of social study for elementary school students in Taiwan still depends on teacher’s one-way instruction. It’s difficult to activate students’ motivation within the limited course time. Approach: This study is proposed to recognize how e-learning improves teaching and learning … …Journal of Mathematics and Statistics, Vol. 7, Issue 2 · 18 May 2011 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractAuthentication Based and Optimized Routing Technique in Mobile Ad hoc NetworksS. Varadhaganapathy, A. M. Natarajan, S. N. SivanandamProblem statement: An Ad hoc network has been defined as a self-organizing, dynamic topology network formed by a group of wireless mobile nodes. Minimal configuration, absence of infrastructure and quick deployment, would make ad hoc networks convenient for emergency situations other than military applications. In recent years, security in Ad hoc Networks as a research topic had started to receive … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopological Decoupled Group Key Management for Cellular NetworksJorge Estudillo Ramirez, Saul Eduardo Pomares Hernandez, Gustavo Rodriguez Gomez, Jose Roberto Perez CruzProblem statement: The continuous increasing capacity of the cellular networks motivates the development of multiparty applications, such as interactive mobile TV and mobile social networks. For these environments, security group services are required. A practical way to provide security services is by using cryptographic methods. However, the key management needed for these methods, which considers a dynamic group membership, introduces … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Scalable and Reliable Cost Effective Key Agreement Protocol for Secure Group CommunicationS. Jabeen Begum, Dr. T. PurusothamanProblem statement: In a heterogeneous environment, for a secure multicast communication, the group members have to share a secret key which is used to encrypt/decrypt the secret messages among the members. The Secure Group Communication of large scale multicast group in a dynamic environment is more complex than securing one-to-one communication due to the inherent scalability issue of group key … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Fatigue and Chronic Ankle Instability on Dynamic Postural ControlSeyed Hossein Hosseinimehr, Hassan Daneshmandi, Ali Asghar NorastehProblem statement: The proprioception information is a prerequisite for balance, body's navigation system and the movement coordinator. The aim of this study was to investigate the effects of fatigue and chronic ankle instability on dynamic postural control. Approach: Thirty physical education students (14 males, 16 females) in two groups (15 healthy age = 21.78±0.79 years, height = 168.3±5.6 cm and … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 8,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Framework for Group Key Management Protocol Assessment Independent of View SynchronyDavid Manz, Paul Oman, Jim Alves-FossProblem statement: As group key management extended into the area of large dynamic networks, complex issues emerged involving the many operations that run over several network topologies. The issues that occurred due to multiple topologies were also compounded by differing views of the network, taken at different time slices or positions within the network. This was especially complex when figuring … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Token-Based Fair Algorithm for Group Mutual Exclusion in Distributed SystemsAbhishek Swaroop, Awadhesh Kumar SinghThe group mutual exclusion (GME) problem is a generalization of the mutual exclusion problem. In group mutual exclusion, a process requests a session before entering its critical section (CS). Processes requesting the same session are allowed to be in their CS simultaneously, however, processes requesting different sessions must execute their CS in mutually exclusive way. The paper presents a token-based … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 7,095 accessesView PDFCite
