A Novel Remote User Authentication Scheme Using Bilinear Pairings
Password authentication is an important technique to verify the legitimacy of a user. The technique is regarded as one of the most convenient methods for remote user authentication. The paper presents a remote user authentication scheme using the properties of bilinear pairings. In the scheme, the remote system receives user login request and allows login to the remote system if the login request is valid. The scheme prohibits the scenario of many logged in users with the same login-ID, and provides a flexible password change option to the registered users without any assistance from the remote system.
