The Study Of Application Of Digital Certificates Based On PKI And Its Application In The Industrial And Commercial System

Information security is always a delicate and pop subject in the field of IT. During the gradual mastery of PKI, specialists are devoted to the study of network security based on PKI. The rapid development of information brings us more challenges.The paper studies the application of digital certificates based on PKI, which is used in the field of network information security.After researched about the principal of cryptography and PKI, the status of application and development of PKI is deeply discussed, and a direction of digital certificates based on PKI is presented.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 secure transmission, 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.
