Abstract
This paper, based on the remote dynamic identification, designs a scheme that can effectively pre-vent user key information leakage, and ensure the authenticated user's access to network services. After a security analysis on the Wen-Li proposed scheme and the key agreement scheme, the paper points out its flaws which may lead to the disclosure of user key information, and then the attacks. On the basis of its advantages, the paper pro-poses a remote user authentication scheme with the redesign of the session key and key authentication process con-firmation. When compared with Wen-Li scheme, the improved scheme can resist the man in the middle attack and the stolen smart card attack, and its security is enhanced.关键词
