摘要: Three-party password-based authenticated key exchange (3PAKE) protocol allows two clients, each sharing a password with trusted server, to establish secret session the help of server. It is practical mechanism for establishing secure channels in communication networks. Recently, Xu et al. proposed 3PAKE without server’s public key. They claimed that their could withstand various attacks. In this paper, we show al.’s insecure against stolen-verifier attack. Furthermore, propose an improved overcome weakness protocol. Security and performance analysis shows our not only overcomes security weakness, but also more efficient. Therefore, suitable applications.
