An Efficient Mobile User Authentication Scheme with User Anonymity for Wireless Communications

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.
