The Research Of E-commerce Security Technology Based On SSL

E-commerce in china started in the late 1990s.After 10 years of development, online shopping, online trading and e-payment become very popular.It's changing the people's life and work.However,because of internet openness, e-commerce has encountered the serious security problem.The security problem had already hindered the e-commerce development. At present,the way that solve the e-commerce security problems mainly based on SSL protocol and SET protocol.These two protocol based on PKI,all have shortcomings.In order to enhance e-commerce transaction security,the thesis proposes an improved scheme,which based on the SSL protocol.The contents of this thesis are as follows:(1) Summarize the knowledge about the SSL protocol and the SET protocol, analyse these two protocols respective characteristics, safety, transaction process.Finally,choose the SSL protocol as a security protocol for e-commerce security transactions.(2) For SSL lack of the function to prevent denied,increased a digital signature module.The module improved the e-commerce transactions process.(3) For SSL lack of the function to verify user identity,designed a verify module based on keyboard input behavior. In addition,increased a verify module based on the items of customer holding.(4) Designed a CA system,which solve the problem of public key authentication.In the end,the thesis realized these improvement scheme modules.Analysis and test indicated that these improvement scheme is feasible. It can effectively solve e-commerce transactions safety problem.
