Recently, the researcher proposed an enhancement on a remote authentication scheme designed by another researcher which emphasizes on using dynamic identity. They claim that their improvement can avoid insider attack. However, the authors found the scheme lacks the anonymity property. Moreover, researcher indicates their scheme also suffers the insider attack. Due to these observations, in this paper they propose a novel one which not only anonymously authenticates the remote user by using only two passes but also satisfies the ten requirements of an authentication scheme using smart card mentioned by researcher.
