Improved Password Mutual Authentication Scheme for Remote Login Network Systems
Password-based authentication schemes have been widely adopted to protect resources from unauthorized access. In 2008, Chang-Lee proposed a friendly password mutual authentication scheme to avoid the security weaknesses of Wu-Chieu’s scheme. In this paper, we have shown that Chang-Lee’s scheme is vulnerable to the forgery attack and password guessing attack, etc. Also, we proposed the improved scheme to overcome these security weaknesses, even if the secret information stored in the smart card is revealed. As a result of security analysis, the proposed scheme is secure against the forgery attack and password guessing attack, etc. And the performance of the proposed scheme is more efficient than that of Chang-Lee’s scheme in terms of the computational complexities.
