Research On Security Small-Scale EP System On-Line Based On Smart Card

Electronic Payment (EP) is not only the key aspect of Electronic Commerce (EC), but also the basic requirements for the shape up of it. Without the proper EP system, EC will be the real "Virtual Commerce", which is market conditions and electronic contract. However, bargains can't be on line under this. What's more, most of the bargains done on line are of small-scale, as a result the prototypes for small-scale should be put forward timely. Just for the biggest challenge for EC is the problem of security and the Smart Card's proper security capability, the research on "Security small-scale EP system on line based on Smart Card" will certainly accelerate EC's development of our country.Firstly, this thesis deal with the introduction of source of the project, the development and status quo of EC and EP systematically and compare several EP systems in detail, the virtue of EP system that based on Smart Card.In sequence, it analyzes the primary principle of Smart Card and especially the inherence mechanism of Chip Operation System (COS), and defines the file structure of this EP system in card.Next, adopt the principle of Web Data Base (DB) programming, especially analyzes these fields such as: Windows Socket programming; the technique of access to DB; the middleware technique of CGI and ASP; the characteristics of C/S and B/S. And it brings forward the distributing B/S model that adopts the middleware technique during this EP system.Moreover, the whole frame of online small-scale EP system is brought out, followed by the introduction of the management system of key. It emphases the realization processes of the various modules of the distribute card system and declares the command streams of the distribute card system.It realizes Security small-scale EP system on line based on Smart Card. In the mean time, it builds User Card Management module, the client of Web Browser can query the information of card in convenience and in real time.Finally, it analyzes the current security malpractices and universal security protection measures that EC faced. It put forward a security e-Mail way thatbased on Smart Card, especially in improving on SET protocol. And it also discusses the security capability of desktop Operation System, gives the security user login management of Windows 98 that based on Smart Card.The whole paper does research on EP system during EC. In accordance with object-oriented principle, it adopts the technique of network, DB and Smart Card to build "Security small-scale EP system on line based on Smart Card". Through this system, the customer can pay on line for the choosing correlative merchandise by browsing the shop's homepage. "Security small-scale EP system on line based on Smart Card" is very easy to adopt. And it has good security performance and quick speed. It suits for the current actuality of Chinese network, success in filling up the blank of our country in secure EP system on line.
