In 2007, Khan-Zhang made an enhancement based on Lin-Lai’s flexible biometrics remote user authentication scheme. The scheme has the merits of providing mutual authentication, no verification table, freely changing password and preventing the server spooling attack. However, this authentication scheme has been found to be vulnerable to the insider attack, the denial-of-service (DoS) attack and the clock synchronization problem. To overcome these weaknesses, a novel authentication scheme is proposed in this paper, which is based on nonce instead of timestamp and fresh tag to overcome the existing DoS attack and clock synchronization problem. The security analysis shows that the improved scheme not only inherits the merits of their scheme but also enhances the security of their scheme. Meantime the improved scheme does not add additional computation cost to the smart card. So the improved scheme is more secure, reliable and applicable with high potential to be used in the insecure network world than Khan-Zhang’s scheme.
