The Research On Electronic Payment System

Recently there has been an explosion of interest in the area of electronic commerce over Internet. It is generally realized that the Internet will not be able to offer full-fledged electronic marketplace capabilities without a suitable electronic mechanism for processing payments. In particular, several protocols dealing with payment for Internet transactions have been proposed, while several others are in development. It is clear that if Internet were to become an open marketplace for goods and services, the need for secure charging and payment is essential. This paper focuses on the research on electronic payment system for Internet transactions. In this paper, we analysis almost every aspect of electronic payment including its development process, its classification, its basic technology, its security requirements and so on. At last we propose a useful and secure payment model based on Concurrent Signatures. At the same time, considering the problem of traceability of electronic cash, we propose a model. In our model, traceability can be easily realized using the special property of the group signature.
