碩士 === 國立交通大學 === 電資學院學程碩士班 === 91 === With growing popularity of network communication and electronic commerce, electronic payment plays a more and more important role in consumption market. Among all electronic payment types, cryptographic on-line credit card type is more secure. But due to the high processing cost and bad performance, it’s not suitable for micro-payment environment. In the daily purchase model, people need to take along with some small-value money to make commodity purchase, to fuel up, or pay for some services. This model will take some drawbacks for Banks, merchants and consumers. Using electronic purse can provide a great benefit for human being. For instance, you don’t need to take coins to shop and merchant will get payment quickly. Furthermore, electronic payment involves a core topic named funds transfer, in which the security and confidentiality are important issues. In comparison with other type of electronic purse, Java card can afford higher security and portability to be as a base on implementation of electronic purse. Making a comprehensive survey of Taiwan’s electronic purse production, because of discrepancy and incompatibility among the electronic purse of specifications and systems, shopping convenience and e-purse promotion are up against obstruction. In other words, people can’t only take one card to make general small-value purchase. For this reason, I implement a electronic purse system combined with advantages of common electronic purse specification and java card. This system suitable for micro-value and off-line payment, contains card and terminal sides programs. Besides, it adopts public-key and secret-key cryptography mechanisms for authentication and secret transportation.
