Research ArticleOpen accessPhrase in the titleAn Efficient Certificate-Free Key Distribution Protocol for Secure Group Communication in Grid EnvironmentMandadi Venkatesulu, Kamatchi KartheebanProblem statement: In grid environment, group communication is an important mechanism to realize large-scale information resource sharing. However providing security for group communication in grid environment is very difficult because the group is dynamic in nature. Scalable group re-keying is one of the important issues in secure group communication. These group keys should be updated whenever a member joins/leaves the … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,125 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA 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 accessPhrase in the titleOPTIMIZING 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 accessEvery word in the titleHybrid 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 keywordsEfficient 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 keywordsAn 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 PDFCite
Research ArticleOpen accessIn the keywordsAn Effective Key Management Approach to Differential Access Control in Dynamic EnvironmentsYogesh Karandikar, Xukai Zou, Yuanshun DaiApplications like e-newspaper or interactive online gaming have more than one resource and a large number of users. There is a many-to-many relationship between users and resources; each user can access multiple resources and multiple users can access each resource. The resources are independent and each resource needs to be encrypted by a different Resource Encryption Key (REK). Each REK … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,770 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTopological 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 abstractAN EFFICIENT AND VARIABLE INTERVAL REKEYING FOR DYNAMIC AD HOC MULTICAST GROUP USING KEY PATH REDUCTIONR. Pugalenthi, T. V. GopalKey distribution is one of the major issues in secure ad hoc multicast group communication. There has been an extensive research on rekeying, to reduce cost. In this study, we propose an efficient and scalable batch rekeying for dynamic ad hoc multicast group, with variable interval and key path reduction techniques. The proposed scheme overcomes the major existing issues like … …Journal of Computer Science, Vol. 10, Issue 7 · 16 Jun 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractGROUP MANAGEMENT IN MOBILE ADHOC NETWORKSK. Senthil Kumar, S. Sasi Kumar, C. SugapriyaIn this study, we proposed an algorithm for Cluster Based Zone Allocation method (CBZA) for energy conservation and packet dropping in mobile ad hoc network. MANET is a self-organized, temporarily dynamic network and their nodes are mobile without using any infrastructure. However, secure communication occurs between group nodes based on cluster method. In multicast routing, group information is shared by … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 22 Apr 2014 · 6,321 accessesView PDFCite
