| Summary: | 碩士 === 中國文化大學 === 資訊管理學系 === 100 === With the development of technology, today, the society use of smart cards is very popular. Smart card is also called chip card, IC card, etc. Insurance cards and financial cards are examples of smart card applications. Generally speaking, the smart card is a small chip embedded on a plastic card with data storage function that can read and re-write the data stored in the card.
The property of non-repudiation is very important in information security. In this study, all the reviewed literatures are without digital signature algorithms and without non-repudiation property. On the other hand, to achieve non-repudiation, today, most mechanisms using smart cards in related literatures apply high cost digital signature al-gorithms.
Therefore, to save cost, this study design a low-cost secure remote authentication scheme using smart card to achieve mutual authentication and non-repudiation property through a trusted registration center. The registration center is involved in the login and authentication process in the scheme to help communicating parities, the user and the server, in checking the non-repudiation evidence provided by each other. With stored effective evidence for non-repudiation, both communicating parities will not be able to repudiate in the future, given the registration center as the trusted third party to perform a fair judgment.
