The Research About The Key Technique Of Exploitation Of E-Commerce City

In this dissertation, based on researching about information transmission encrypting using SSL protocol and safe authentication using PKI mechanism, the following three problems are mainly discussed:Firstly, the basic architecture form of E-Commerce City and the general process trading from WEB are given, furthermore, this process is applied to the system of "YinZuo E-commerce City" .Secondly, safe technique of trade from WEB is investigated based on the system of E-commerce City. For the safe transmission of data and the identity authentication are the mainly safe mechanisms of E-commerce City, therefore two kinds of identity authentication mechanisms are adopted in the system of "YinZuo E-commerce City" (one is the Challenge-Response solution when the clients login the network station of E-commerce City, another is the mutual authentication by digital signature solution between the electronic banks), and they are made to implement by SSL protocol.Finally, the authentication system based on CFCA PKI is studied, and it is applied to the study of the identity authentication of system client and the safety transmission of defraying data from WEB.
