They also demonstrated that their scheme could overcome various attacks. In this paper, the security of Wang etal.'s scheme is evaluated. Our analysis shows their scheme is vulnerable to the server spoofing attack, the impersonation attack, the privileged insider attack and the off-line password guessing attack.
