Research ArticleOpen accessEvery word in the titleSecure Group Key Management for Dynamic Sensor NetworksN. Suganthi, V. Sumathi, R S. MohanapriyhaProblem statement: Key management is an important cryptographic technique for providing security in a dynamic environment of sensor networks. To provide a secure communication among a group of sensor nodes keys should established in an efficient manner. We introduced an efficient and dynamic key management system for dynamic sensor networks. Approach: We pre deployed some of the keying materials in … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,743 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHIERARCHICAL ACCESS CONTROL IN DYNAMIC PEER GROUPS USING SYMMETRIC POLYNOMIAL AND TREE BASED GROUP ELLIPTIC CURVE DIFFIE HELLMAN SCHEMEKumar Krishnan, Sumathy Vembu, Nafeesa Begum JeddyHierarchical Access Control in group communication is an active area of research which is difficult to achieve it. Its primary objective is to allow users of a higher authority group to access information or resource held by lower group users and preventing the lower group users to access information held by higher class users. Large collection of collaborative applications in … …Journal of Computer Science, Vol. 10, Issue 9 · 15 Apr 2014 · 6,999 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAN 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 keywordsAn 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 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 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 abstractOn the Sensitivity of a Dynamic Measure of Financial InequalityGuglielmo D’Amico, Stefania Scocchera, Loriano StorchiIn the present work, we investigate the sensitivity of the dynamic Theil index computed under a Markov reward model with respect to structured perturbations affecting the underlying Markov process. The model is applied to the sovereign credit spread evolution as a proxy for financial risk, which are driven by the sovereign credit rating dynamic. The introduction of such perturbations allows … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Oct 2019 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractForces of a 3R RobotRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.In this study, one presents a method for determination of kinetostatic parameters in dyad 3R. It starts with the determination of the forces in the joints: RB, RD, R23. To generalize the method including for the 2R robots, enter both the moments M1, M2. This module (2R) is the main module found in all rotating anthropomorphic robotic structures and similar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 1 · 8 Nov 2017 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractInter Cluster Group Management in Wireless Sensor NetworksR. Rohini, Adamu Murtala Zungeru, S. Ravi, Dasari Narasimha RaoWireless Sensor Networks (WSNs), an emerging large-scale network system can be embedded for any application. The designers of wireless sensor network have to consider the quality of service agreements from a user perspective. The WSN is very rapid in dynamic changing topology and has less energy, computing and communication resources. The network design has to fulfill the QoS parameters like … …Journal of Computer Science, Vol. 14, Issue 4 · 19 Apr 2018 · 7,988 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
