In 2000, Sun proposed an efficient remote user authentication scheme using smart cards without requiring a password table. However, the password of a user is an un-human lengthy p...
In this paper, we propose a cost effective mutual authentication scheme with key agreement using smart cards. Our scheme is motivated by the scheme design in two articles publishe...
Abstract—In this work we consider two protocols for performing cryptanalysis and security enhancement. The first one by Song, is a password authentication scheme based on smart ...
