System and method for extending secure authentication using unique session keys derived from entropy generated by authentication method

摘要

The present disclosure relates generally to the field of communications systems, and more particularly, to a system and method for extending secure authentication using unique session keys derived from entropy generated by authentication method. In one example, a method for utilizing a public wireless local area network for a client with a smart card includes: creating an one-time password for a client upon a successful authentication; storing the password and identification information of the client; and utilizing the password and the client identity information to authenticate the client in the public wireless local area network.
