Due to various kinds of threats exist on the Internet, for example, there might be an illegal person who wants to steal some secret information not belonging to him from the Internet, it is the very urgent to develop a safe and effective mechanism.

Our goal is to propose an effective method to frustrate the various attacks and other malicious damages in the login and authentication phases between an user and a remote system. Our method of a password table and a smart card which make our mechanism portable, secure and convenient. Thus, we make a much more reliable circumstance on the Internet.
