In 2000,a remote user authentication scheme using smart cards was proposed and the masquerade attacks were proved successful on this scheme.Recently,Kumar has suggested the idea of check digits to overcome the above attacks with a new scheme that removes these threats well.In this paper it is pointed out that the weakness still exists in Kumar’s scheme,and the intruder can login to the remote system through having some information.A new scheme which can overcome these attacks and appears more secure and efficient than Kumar’s is presented.
