At the same time identity and password based authentication schemes are no longer adequate because of the insecurity of user identity and password. As a result biometric user authentication has emerged as a more reliable and attractive method. However, existing biometric authentication schemes are vulnerable to some common attacks and provide no security proof, some of these biometric schemes are also either inefficient or lack sufficient concern for privacy. In this paper, we propose an anonymous and efficient remote biometric user authentication scheme for a multi-server architecture with provable security. Through theoretical mathematic deduction, simulation implementation, and comparison with related work, we demonstrate that our approach can remove the aforementioned weaknesses and is well suited for a multi- server environment.展开更多

User's verifier information stored on the single server is a main point of susceptibility and remains an attractive target for the attacker. On the other hand, multi-server architecture based authentication protocols make it difficult for the attacker to find out any significant authentication information related to the legitimate users. In 2009, Liao and Wang proposed a dynamic identity based remote user authentication protocol for multi-server environment. However, we found that Liao and Wang's protocol is susceptible to malicious server attack and malicious user attack. This paper presents a novel dynamic identity based authentication protocol for multi-server architecture using smart cards that resolves the aforementioned flaws, while keeping the merits of Liao and Wang's protocol. It uses two-server paradigm by imposing different levels of trust upon the two servers and the user's verifier information is distributed between these two servers known as the service provider server and the control server. The proposed protocol is practical and computational efficient because only nonce, one-way hash function and XOR operations are used in its implementation. It provides a secure method to change the user's password without the server's help. In e-commerce, the number of servers providing the services to the user is usually more than one and hence secure authentication protocols for multi-server environment are required.展开更多
