A Biometrics-Based Remote User Authentication Scheme Using Smart Cards

Biometric technology is an important characteristic and a reliable authentication method, which can be used to verify the user's identity for its accessibility and uniqueness. In this paper, we analyze the existing protocols and find that they still have some security flaws. In order to effectively enhance the security, we present a biometrics-based remote user authentication scheme using smart cards to overcome those weaknesses. According to security and cost analysis, compared with other authentication schemes, the proposed scheme costs 21T(h). However, it can implement more security goals and withstand different attacks, such as DoS attack, anonymity attack and leak of verifier attack.
