Summary :

In 2003, Wu and Chieu proposed a scheme that was claimed to be an enhanced version of Sun's password authentication scheme. Recently, Wu and Chieu themselves showed that their scheme is vulnerable to a forgery attack and then proposed an improved scheme. Herein, we demonstrate that Wu-Chieu's improved scheme is still vulnerable to several attacks.
