ABSTRACT: In recent trends smart cards are used as electronic wallets. Because smart card brings comfortable to the users and also smart card increases the risk, when the card holder lost the card. If the smart card is affected by an attacker, the attacker will try to analyze the secret information within the smart card or break the entire authentication system. So we need smart card based password authentication scheme for providing the security to the smart card. Cryptographic protocols protect the exchange of money between the smart card and the machine. In our proposed scheme involves a server and a user, and typically consists of three phases. The first phase is called the registration phase, an initial password for the user is also determined (chosen by the user or by the server). Once the registration phase is completed, the user is able to access the server in the log-in phase, which can be carried out as many times as needed. A successful log-in requires the user to have the v
