Cryptanalysis of and Improvement on Biometric-based User Authentication Scheme for C/S System

Younsung Choi, Dongho Won

Abstract: Password-based authentication schemes are convenient, but vulnerable to simple dictionary attacks. Cryptographic secret keys are safe, but difficult to memorize. More recently, biometric information has been used for authentication schemes. Das proposed a biometric-based authentication scheme, but it has various vulnerabilities. Jiping et al. improved Dasís scheme, but some vulnerabilities remain. In this paper, we analyze the cryptanalysis of Jiping et al.ís authentication scheme and propose the security enhanced biometric-based user authentication scheme for the C/S System.
