This paper discusses the security for a simple and efficient three-party password-based authenticated key exchange


protocol proposed by Huang most recently. Our analysis shows her protocol is still vulnerable to three kinds of attacks: (1)


undetectable on-line dictionary attacks; and (2) key-compromise impersonation attack. Thereafter we propose an enhanced


protocol that can defeat the attacks described and yet is reasonably efficient
