A Biometric based Remote User Authentication Technique Using Smart Card in Multi-Server Environment

Remote user authentication is an efficient technique to perform secure communication over an insecure network.In this current research article, a lightweight remote user authentication scheme using smart card is proposed. The proposed scheme is a multi-server authentication mechanism where user biometric plays a prominent role. Here, the user is provided the freedom of selecting his or her service according to its requirement. Registration center selects the server according to the service selected by the user and provides a handshaking between user and server. Both user and server have to mutually authenticate each other to an authorized registration center by message passing. By this technique, finally a session key is generated which is used to perform further communication. Security analysis of the proposed method proves its robustness and comparative analysis with some existing schemes provides the superiority.
