A MULTI-SERVERS REMOTE USER AUTHENTICATION SCHEME USING A SMARTER SMART CARD

To most Internet users, multiple combinations of accounts and passwords are hard to manage and they simply stick to one password for all accounts. However, it will cause a higher risk for those user accounts. In this paper, we propose a remote user authentication protocol based on a smarter smart card. Our protocol is convenient to users within a multi-server environment. With our proposed protocol, users can build a Single Sign-On (SSO) service on his smart card. Our protocol is also convenient for the server to be integrated in our SSO-like mechanism with low cost.
