Abstract
Recently, Wang-Chang proposed a password authentication scheme for implementing a remote access network system whose security rests in part on the difficulty of factoring a large number and discrete logarithm problem. This paper presents that Wang-Chang's smart card based password authentication scheme is insecure against two impersonation attacks and the off-line password guessing attack.
