Strongly Password-Based Three-Party Authenticated Key Exchange Protocol

Abstract

Password-based authenticated key exchange (PAKE) is applied widely in modern communication because that password is easy to be remembered and system has good scalability. But most of the existing PAKE protocol cannot meet the proposed security attribute. In this paper, we propose a strongly password-based three-party authenticated key exchange (3PAKE) protocol based on the Diffie-Hellman key exchange idea and a one-way hash function, and give a variant. At last, we show the proposed protocol is secure and it can meet a series of security attributes.
