Abstract

Authenticated key exchange protocols have an important role for building  secure communications amongst two or more entities over the networks. Two party authenticated key exchange protocols where each pair of parties must  share a secret with each other; a three-party protocol does not cause any key  management problem for the parties. In this paper, an extension of two-party  key exchange protocol, which is based on Diffie-Hellman key exchange. is  proposed. In this protocol each user exchanges secret key with server then each  user uses this secret key to exchange session key with each other. The  efficiency and the security analysis of this new key exchange protocol are  proven in this paper.
