Multiple Key Exchange Protocol with Strong Security
Zhang Shi-wu
Abstract
All existing two party multiple key exchange protocols cannot resist ephemeral key compromise attack.To solve this problem,a new two party authenticated key exchange protocol based bilinear map is proposed for enhancing the security and efficiency of two party key exchange protocols.Four different session keys can be computed through one session of the proposed protocol.Compared with existing protocols,the new protocol with stronger security can resist ephemeral key compromise attack and provide mutual authentication.
