Abstract

User authentication is an operation whereby one user is aware of the identity of an another user involved in a protocol. In 2004, Park presented an authentication protocol providing user anonymity based on the secret-key certificate and error-correcting codes called PA protocol. In this paper, it will be argued that PA protocol is vulnerable to the man-in-the-middle attack and does not provide a sufficient level of security. Then, an improved protocol to fix this problem is proposed.
