Abstract: SUMMARY In this paper, we first showed that Lou and Huang's three-party password-based key exchange protocol is still vulnerable to offline dictionary attacks. Thereafter, we proposed an enhanced protocol that can defeat the attack described and yet is efficient. Finally, we provided the rigorous proof of the security for it.
