An Enhanced Biometric-Based Three Factors User Authentication Scheme for Multi-server Environments
Youping Lin,Kaihui Wang,Baocan Zhang,Yuzhen Liu,Xiong Li 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.1
Authentication is an important and basic security service for many network based applications, which allows the registered user access remote services after the validity of his/her identity is verified by the remote server. Password, smart card and biometric are three frequently used factors in authentication, and some remote user authentication schemes for different environments had been presented based on these factors by researchers. Recently, Baruah et al. pointed out the weaknesses of Mishra et al.’s three factors user authentication scheme for multi-server environments, and they proposed an enhanced scheme. They claimed that their scheme has many security features and can resist some common attacks. However, based on our analysis, Baruah et al.’s scheme cannot resist stolen smart card attack, cannot protect user’s anonymity, and it is also vulnerable to Denial of Service attack. In this paper, an enhanced three factors user authentication scheme for multi-server environments based on fuzzy extractor technology is proposed, and the analysis show that the proposed scheme is more security and efficient than other related schemes.
