Modeling and Performance Analysis for User Authentication Scheme based on Anomaly Detection Method

Recently, many mobile user authentication schemes with user anonymity for wireless communications have been proposed. In 2012, Li and Lee proposed a novel user authentication and privacy preserving scheme with smart cards for wireless communications. In 2013, Jeon et al. proposed an improved user authentication scheme, and claimed their scheme achieves user anonymity and more efficient. On the basis of their work, we put forward a new user authentication scheme using elliptic curve cryptography with user anonymity for wireless communications. The security and performance analysis show that the new scheme is more secure and efficient for wireless communications.

In 2011, Lee et al. analyzed the security weaknesses of Hsiang et al.s scheme and proposed a security dynamic ID-based multi-server remote user authentication scheme. They claimed that their protocol is secure and efficient. However, we observe that Lee et al.'s scheme is still vulnerable to stolen smart card attack, malicious server attack. To remedy these security weaknesses, we propose an improved dynamic ID-based remote user authentication scheme for multi-server environment. Besides, security analysis and performance analysis show that compared with other remote user authentication schemes, the proposed scheme is more secure and possesses lower computation cost. As a result, the proposed scheme seems to be more practical for users with portable mobile devices in multi-server environment.

And Performance

One new concept, "directed" authentication is presented in this letter. By "directed", we mean "of one direction", i.e., only the specified verifier can validate the verifiee's identity, anyone else cannot verify it without the help of this specified verifier. One strong directed authentication scheme based on the discrete logarithm is proposed in this letter, and the security and performance of which are also analyzed. It is shown in this letter that the proposed scheme is secure and the performance is superior to those of the mutual authentication schemes based on ID-based cryptosystems.
