Title: Strengthening Dynamic Identity Based Remote User Authentication Scheme Using Smart Card against Offline Password Guessing Attack
Abstract: The use of smart cards began in the 1980s and since then the use of its technology was increasing. Since the smart card is used for securing transaction, then security issue in the smart card becomes important. However, there are problems with smart card security such as smart card forging, user impersonation, user's identity theft, etc. To overcome the smart card's problem, dynamic identity based authentication scheme is introduced. Wang et al [1] proposed a scheme which is secure against offline password guessing attack. However, Zhaiet al [2] claims that Wang et al.'s scheme still has vulnerability to offline password guessing attack. This research proposed a new scheme to strengthen Wang et al.'s scheme against offline password guessing attack. The proposed scheme used a random number u and Diffie-Helman key exchange [3] for securing the user's password. The proposed scheme has been proven stronger than Wang et al.'s scheme against offline password guessing attack since the probability of success in guessing the user's passwordon the proposed scheme is lower than Wang et al.'s scheme while preserving the strength against user impersonation attack.
