Robust Mobile Device Integration of a Fingerprint Biometric Remote Authentication Scheme

Communications in the wireless environments such as GSM, CDPD, 3G, and 4G are very popular. Therefore, it is necessary to have a secure authentication scheme to protect transactions between users and servers from illegal adversaries. Especially, users are people vulnerable to attacks and there are many authentication schemes with smart cards proposed to guarantee them. Recently, Chen et al have proposed a scheme integrated with fingerprint of users to enhance security for authentication. With this idea, Chen et al.´s scheme truly is more secure than previous ones. However, their scheme is easy to be compromised by replay attack. Furthermore, attackers can steal identity to re-register to obtain secret key to fake users and servers. In this paper, we present an improvement to their scheme in order to isolate such problems.
