Recently, Jeong et al. proposed a strong Diffie-Hellman-DSA key exchange scheme providing security against session state reveal attacks as well as forward secrecy and key independence. The current paper proposes an efficient Diffie-Hellman-MAC key exchange scheme providing same securities. The proposed scheme is based on the keyed MAC hash function to provide efficiency.
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.
