Secure Group Communication based on Elliptic Curve Cryptography

Abstract

Group key management is an important functional building block for any secure multicast architecture. In this regards, it is identified some security issues in the group key management when a user join or leave the group then forward secrecy and backward secrecy issues comes in the multicast networks. This paper provides an efficient and improve mechanism for group key management solutions with computational and communication overhead are less while rekeying cost also minimize
