Cryptanalysis of A Secure Remote User Authentication Scheme Using Smart Cards

Smart card based authentication schemes are used in various fields like e-banking, e-commerce, wireless sensor networks, medical system and so on to authenticate the both remote user and the application server during the communication via internet. They have used a secure identity mechanism i.e., users' and server's identity are not public. Thus, the user and the server do not send their identity directly to each other during communications. In this paper, the authors have found out that their scheme does not overcome the reply attack and also there is a fault in the login phase, which makes their scheme, is not perfect for practical use.
