Abstract :
Password-authenticated key exchange (PAKE) allows the participants to share a session key using a human- memorable password only. In this paper, A provably- secure password-based authenticated tripartite key exchange protocol(3-PAKE) is presented in the standard model. The security of the protocol is reduced to the Decisional Bilinear Diffie-Hellman (DBDH) problem, and the protocol provides not only the properties of forward secrecy, but also resistance against known key attacks.
