Abstract
With the popularity of group-oriented applications, secure electronic communication among all group members has become a major issue. This paper proposes a distributed group-oriented key management scheme for secure electronic communication. The scheme deploys Elliptic Curve Diffie-Hellman (ECDH) which is more lightweight as compared to regular Diffie-Hellman. According to the security analysis, the proposed scheme provides a number of desirable security properties, including group key secrecy, forward secrecy and backward secrecy.
