Secure Group Communication with Low Communication Overhead using Effective Multicasting
International Journal of Emerging Engineering Research and Technology · 2017
Multicast networking support is becoming an increasingly important future technology area for both commercial and military distributed and Group based applications.Secure Group communication deals with the exchange of information between authorized group members.Security of packets delivered from a source to a large group of receivers presents one of most challenging problem for the network architecture.A majority of proposals for scalable secure multicasting makes use of hierarchal key distribution trees.In this paper we proposed a protocol with a lower communication cost for secure group key management called "N-Sec Cumulative Rekeying Protocol".The protocol is based upon the use of key trees for secure group and periodic batch rekeying.
