An Efficient and Reliable Time Variant Three-Entity and Data Authentication of Remote User Using Smart card

Authentication of remote user needs research and investigation due to increasing security threats and attacks with the increasing volume of wired and wireless traffic. All of the popular password-based remote user authentication are fixed authentication and checks the authenticity of user by only user password and id. They provide only entity authentication, not any data authentication. This paper is a proposal of time variant three-entity and data authentication technique that will check the authenticity of remote user time to time by user password, identifier and biometric property and serves as entity authentication as well as data authentication. We have implemented automatic variable password (AVP) by changing the password time to time. We shows that how AVP enhances the security of our technique. This paper also reports that our time variant three-entity and data authentication technique is more efficient than other fixed authentication techniques.
