When user wants to access a network service, he/she must authenticate his/herself to the server. With the increasing of the different network services, it is extremely hard for user to remember the different ID and password, so the multi-server authentication protocols have been proposed to solve this problem. There are some authentication protocols for multi-server architecture using smart cards, but there are some serious secure problems in their schemes. The protocols they proposed cannot resist the replay attack, the impersonation attack, etc. So we propose a multi-server architecture authentication protocol with dynamic identify and smart card based on Lee et al.'s scheme. Our protocol can resist several kinds of attacks and remove the aforementioned weaknesses of their protocol. In this paper, we first provide a brief view of the multi-server architecture which is used in the authentication protocol, then we propose our multi-server architecture authentication protocol and give a security analysis of our proposed protocol, finally we make a comparison with our protocol and some other multi-server architecture authentication protocols.
