Abstract :Remote mutual authentication is an important part of security, along with confidentiality and integrity, for systems that allow remote access over untrustworthy networks, like the Internet. In 2006, Shieh-Wang pointed out the weakness of Juang`s remote mutual authentication scheme using smart card and further proposed a novel remote user authentication scheme using smart card. However, this paper demonstrates that Shieh-Wang`s scheme still does not provide perfect forward secrecy and is vulnerable to a privileged insider`s attack. We also present an improved scheme based on the Elliptic Curve Diffie-Hellman problem insert ignore into journalissuearticles values(ECDHP); and secure one-way hash function, in order to isolate such security problems.
