The authors apply LU decomposition of matrices to present an anonymous bilateral authentication scheme. This paper aims at improving security and providing more excellent performances for remote user authentication scheme. The proposed scheme can provide bilateral authentication, session key agreement, can quickly check the validity of the input password, and can really protect the user anonymity. The security of the proposed scheme is based on the Discrete Logarithm Problem (DLP), Diffie-Hellman Problem (DHP) and the one way hash function. It can resist various attacks such as insider attack, impersonation attack, server spoofing attack, stolen smart card attack etc. Moreover, the presented scheme is computationally efficient for real-life implementation.
