Robust Biometrics Based Three-Factor Remote User Authentication Scheme with Key Agreement
Xiong Li, Jianwei Niu, Muhammad Khurram Khan, Junguo Liao · 2013
Recently, An pointed out the weaknesses of Das's three-factor remote user authentication scheme, and proposed an improved biometric based three-factor remote user authentication scheme. An's scheme improves the security problems of previous schemes while keeping the efficiency. However, after detailed analysis, we find that An's scheme exists some weaknesses such as vulnerable to denial-of-service (DoS) attack and forgery attack, and does not provide session key agreement. In order to provide high-level of security and more useful functions, we design a new robust biometric based three-factor remote user authentication scheme with key agreement using elliptic curve cryptosystem.
