Research Of Railway E-commerce Electronic Payment System

Internet's rapid popularity just like a exploding in recent years, make E-commerce be the most potential factor of IT in future, and bring on a revolution to traditional business.Secure factor is an unneglectable keystone in many factors of E-commerce's developping. So, at first this text introduces two currently main electronic secure payment protocol, secure socket layer (SSL) protocol and secure electronic transtction (SET) protocol. After discussing the process of electronic payment, which is based on the two protocols seperately, this text compares the two protocols' own shortcomings and strongpoints.After analysing the function, which railway passenger ticket electronic payment system should possess, this text analyses railway passenger ticket electronic payment system's designing request from three aspects, construct request, function request and capability request. Then this text narrates the basic proess of railway passenger ticket electronic exchange. On this base, through analysing the particularity of railway passenger ticket electronic payment system, I design the whole framework of railway passenger ticket electronic payment system. This sytem is based on three layers B/S' structure, can sustain the two main secure electronic payment protocol at the same time, has enough security and good expansibility, agility, adaptability, and can sustain several railway E-commerce applications of passenger ticket, package, and freightage after expansion.Then, this text narrates railway passenger ticket electronicpayment system's parts'designing and realization particularly, electronic wallet. This text decribes the datastructure of the data, which is transferred between server and user, this transfer is a representative transfer which is based on SET payment system. At last, this text narrates the realization of using SSL protocol to communicate with server, and narrates the electronic wallet's realization and procss dealing with every message when it uses SET protocol to commucation.
