碩士 === 東海大學 === 數學系 === 98 === In recent years, the demand for information and electronic services is growing. Already the exchange of sensitive information, such as credit card numbers and bank transactions, over the Internet is common practice. Protecting data and electronic systems is crucial to our way of life. The paper is divided into three chapters. The first chapter describes the development of the cryptographic system in the daily life, and the application of the e-commerce such as electronic cash, e-bidding. The second chapter gives the basic knowledge on cryptography such as RSA Algorithm, elliptic curve and the hash function, we also introduce electronic bid for two categories: public bid and sealed bid. Finally, we apply the RSA and elliptic curve cryptography to the sealed bid, and also study the differences between these two methods in the last chapter.
