| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士班 === 100 === Smart card, also called IC card or chip card, was first invented by the German scientists Jurgen Dethloff and Helmut Grotrupp, who added the identity card with integrated circuits and obtained a patent in the same year.
In 1975, the French company CII-Honeywell Bull produced the first credit card that was like ID card. In the same year, French scientists Roland Moreno obtained the patent of IC card in French.
In 1976, the French computer company Bull produced the products of IC card first and began to apply in various areas, just like E-purse, IC debit card, credit card, easy card, national health insurance IC card, natural person''s evidence and so on.
Since the data of smart card will transmit over the Internet, there are some problems to cope with. For example, the transmission of data channels is unsafe; it is easy to be monitored or intercepted the user’s data by the attacker or to perform some of the Internet attacks, like replay attack, masquerade attack, man-in-the-middle attack, and so on. Furthermore, the data stored in smart card can be retrieved by the attacker to launch other attacks, resulting unsafe transactions. Although many scholars proposed their method to improve the security of authentication schemes, there are some weaknesses found by other scholars. Hence, improvements of security of authentication schemes become an endless cycle.
In this thesis, we propose an authentication scheme to improve other methods proposed by other scholars. We assume that the data stored in smart card can be obtained by the attacker, and our scheme can resist various attacks.
