The scheme is very elaborate since no password table is required to keep as well as low communication and low computation costs. However, the password of a user has to be computed by the sy

โฆ Synopsis
this article, we propose a simple remote user authentication scheme using smart cards. This scheme has the following features. First, it does not require any password or verification tables, Second, it can withstand the message replay attack. Third, any legal users can arbitrarily choose and change their own passwords at will. And finally, the password of a user is not revealed to the server. In addition, the computational costs of this scheme are less than those of any previously proposed schemes.
