In recent 2012, Wen and Li.'s has presented a dynamic ID-based remote user authentication with key agreement scheme. They claimed that their scheme can resisted insider attack and provide anonymity for the users. However, Juan Qu and Li-min Zou., described that Wen and Li.'s scheme could not withstand insider attack, does not provide anonymity for the users, and inefficiency for error password login. A different approach to symmetric cryptology is taken in this study to resolve the fore was made Compared to Juan Qu and Li-min Zou scheme, a different approach was made with symmetric cryptology in this study to supplement the forementioned weak points. We propose an enhanced authentication scheme, which covers all the identified weakness of Wen and Li.'s scheme and an efficient user authentication scheme that preserve perfect anonymity to both the outsider and remote server.
