摘　　要：This paper analyzes the security performance of a latest proposed remote two-factor user authentication scheme and proposes an improved scheme based on the dynamic ID to avoid the attacks it suffers. Besides this, in our proposed scheme the password is no longer involved in the calculation of verification phase which makes our scheme more secure and costs less than the old one. At last we analyze the performance of our proposed scheme to prove it provides mutual authentication between the user and the server. Moreover, it also resists password guessing attack, server and user masquerade attack and replay attack effectively.This paper analyzes the security performance of a latest proposed remote two-factor user authentication scheme and proposes an improved scheme based on the dynamic ID to avoid the attacks it suffers.
