The Implementation Of PKI CA And The Application Of It In E-Commerce

Public Key Infrastructure, based on public key cryptography, is a set of hardware, software, humans, policies and procedures which aim at creating, managing, storing, publishing and revoking certificates. This architecture has been applied in many secure application policies.Eommerce does business with electronic measures. It greatly increases the efficiency of commercial transaction by prompt manners and low cost. However, the wide application of Eommerce is limited by the secure problem for it runs on open networks. So it should be built on secure information platforms. Public Key Infrastructure does meet this satisfactory.In this thesis, we analyze elaborately of running mode and secure requirements of Eommerce and deeply research on the Public Key Infrastructure. We implement a Certificate Authentication composed of a CA, a RAServer, RAs and a Secure (Web) Server and define the structure of certificate and running procedure appropriate to Eommerce application. We do a profitable experiment in this area.
