In 2011, Lee et al. analyzed the security weaknesses of Hsiang et al.s scheme and proposed a security dynamic ID-based multi-server remote user authentication scheme. They claimed that their protocol is secure and efficient. However, we observe that Lee et al.'s scheme is still vulnerable to stolen smart card attack, malicious server attack. To remedy these security weaknesses, we propose an improved dynamic ID-based remote user authentication scheme for multi-server environment. Besides, security analysis and performance analysis show that compared with other remote user authentication schemes, the proposed scheme is more secure and possesses lower computation cost. As a result, the proposed scheme seems to be more practical for users with portable mobile devices in multi-server environment.
