碩士 === 逢甲大學 === 資訊工程學系 === 90 === In the real world environment, there are always some malicious persons wanting to steal others’ secret information. Thus, the security problems will occur. In order to against any kind of possible malicious depredations, several mechanisms are employed to verify the legality of the users, one such case, is the mechanism of personal password authentication code. The password authentication scheme provides the basic security and verification applications for users and has been particularly popular for a long time because of it’s simplicity and convenience. However, the weak security is always the main drawback of this method. Due to the recent, rapid progress of industrialized techniques, the capability of the smart card has become ever more powerful. Hence, to utilize the function of smart card combining with password authentication scheme is largely applied to the aspects of business transactions, such as personal identity-authentication card, cash card, credit card and so on. In this thesis, we focus on the password authentication scheme based on smart cards. Thus, by utilizing the portability, security, and convenience of the smart card, we further propose a series of related researches and improvements about password authentication scheme, and then make all improved and proposed schemes to suit for the real world environment.
