Abstract
The present invention discloses a method and system for remote password based authentication using smart cards for accessing a communications network. The disclosed method does not require a remote authentication sever to maintain a table of passwords for all users. The disclosed method and system also support mutual authentication. It not only prevents the illegal use of system resources by an impersonator, the user can also authenticate the identity of the remote authentication server.
