Cryptanalysis and security enhancement of a 'more efficient & secure dynamic ID-based remote user authentication scheme'
2011
Computer Communications
Remote user authentication is a method, in which remote server verifies the legitimacy of a user over an insecure communication channel. Currently, smart card-based remote user authentication schemes have been widely adopted due to their low computational cost and convenient portability for the authentication purpose. Recently, Wang et al. proposed a dynamic ID-based remote user authentication scheme using smart cards. They claimed that their scheme preserves anonymity of user, has the features
