Adaptive Rekeying for Secure Group Communication Using Key Management Technique
Secure and reliable group communication is an active area of this paper. The main problem in secure group communication is group dynamics and key management. It focuses on trade-offs between storage cost and rekeying cost for secure multicasting. Membership in secure multicast group is dynamic and requires multiple updates in a single time frame. A scalable secure group communication model ensures that whenever there is a membership change, a new group key is generated and distributed to the group members with minimal computation and communication cost.
