The Study Of Application Of Digital Certificates Based On PKI And Its Application In The E-government Affairs System Of The Culture Information Web

Public Key Infrastructure , based on public key cryptography, is a set of hardware, software, policies and procedures which aim at creating, managing, storing, distributing and revoking certificates. PKI has been applied in many secure application protocol.Based upon all of above, the paper puts forward an effective scheme of the secure E-government, which used the technologies of X.509 digital certificates, digital signature and public key encryption related with SSL protocol. These technologies have technically ensured the identification, the securetransmission, the authenticity, and the coherence of data in the E-government affairs. A safer and more convenient system has been set up.Through the study of the principle, the application and the scheme design of PKI, techniques of digital certificates application are concluded, which impulses the development of PKI and network security.
