Analysis and enhancements of an efficient biometric-based remote user authentication scheme using smart cards
Résumé
Recently, many biometrics-based user authentication schemes using smart cards have been proposed to improve the security weaknesses in user authentication system. In this paper, we analyze the security of An's authentication scheme [9], and we show that An's authentication scheme is still insecure against various attacks. To fix the security problems identified we propose an enhanced scheme. A detailed security analysis of the proposed scheme is presented followed by its efficiency comparison. Furthermore, we formally proof the security of the enhanced using AVISPA tool.
