The Research And Simulation About System Structure Of Security Network Payment

Because of E-commerce provides more information,more simple transaction,more cheaper cost,it become more popular among the huge number of the users,and it become the mainstream business model and philosophy.Because the network payment is an important link in the process of electronic commerce,how to build a secure network payment system structure of electronic commerce research priority among priorities,when the electronic commerce become more polupar.This article analysis the security problem about network payment of electronic commerce,elaborated the design process and system analysis about the simulation of secure internet payment system,and also made a detailed explanation to the key technology used in the process of implementation of the system.Through the simulation of the actual e-commerce transactions,this article made a further research to the system structure of network payment of electronic commerce,and completed the analysis and design about this system,and then implemented it.This article analyzed the current situation about e-commerce security technology research in China and abroad,this was based on the knowledge of e-commerce security technology.According to the characteristic and the development status of e-commerce,this article explored the security issues of electronic commerce,and introduced the knowledge and technology of security network payment system.This paper focused on the analysis of the characteristics of SSL and SET protocol in security protocols,and proposed a security network payment system model with the advntages of this two protocols through the comparison of the two protocols.Also,this paper analyzed the advantages and disadvantages of RSA and DES algorithm which is used for data encryption,then proposed a hybrid encryption algorithm to avoid the deficiency between both of them.This article constructed a secure Internet payment system,and this system is using a hybrid encryption and a combination of SSL and SET protocols.Also,the system function was implemented.Take this system as the example for simulation,this article analysis the system structure of network payment in electronic commerce,and the analysis about main functions and workflow are introduced.Then,made a simulation of the system function model and database,and implemented some part of key techniques which used in this system..This simulation system can be used for the theoretical research of securty network payment system,and also it can be used for the teaching of network applications.
