Efficient and Secure Password-based Authenticated Key Exchange Protocol
Shuhua Wu, Yuefei Zhu · 2006
Due to the low entropy of human-memorable passwords, it is not easy to conduct password authenticated key agreement in a secure manner Though there are many protocols achieving this goal, they may require a large amount of computation especially in the augmented model which is contrived to resist server compromise. In this paper, we propose a new practical password authenticated key exchange protocol that is efficient and generic in the augmented model. Our scheme is considered from the practical perspective (in terms of efficiency) and is provably secure under the Diffie-Hellman intractability assumptions in the random-oracle model
