Anonymous and Authentication Protocol For Multi-Server
摘要：
In a multi-server environment, when a user wants to login to a different server to access services, he/she needs to register another user identity and password. Recently, the single sign-on authentication method has been proposed. The major characteristic of this method is that a user only needs to remember one identity and password which can login to different servers. This reduces user inconvenience and server resource usage. On the other hand, anonymity is an important issue. If a user’s identity is disclosed, an attacker can trace or masquerade as the user to login servers. Preventing disclosure of the user’s identity is very important. In this paper, we will propose an anonymous and single sign-on authentication scheme based on Lagrange interpolating polynomial for a multi-server environment. According to our security analysis, this proposed scheme maintains anonymity, provides mutual authentication and also resists many attacks such as lost smart card, insider attack and replay attack.
