The Research And Implementation Of The Mechanism Of Issuing User Certificate In Public Key Infrastructure (PKI)

With the information age's coming, man's life is changed largely. Especially with the development of the information technology and the wide application of internet, man's life is being changed momently. AT the same time, E-Business and E-Government become very popular in Internet. And people have the greater and greater secure need to the activity of internet. PKI(Public Key Infrastructure), which is based largely on cryptographic theory and provides mainly the services of authentication and confidentiality and integrality and non-repudiation, turns into the very important secure platform of authentication and authorization in network application and guarantees the information security of the network activity to people. PKI records people's identities into public key certificate. According to a serial of protocols and sandards, It issues the standard X.509 cerificate for user in order to apply it into the normal network activity and consequently guarantees the validity and the security of user's network activity. This thesis mainly researchs the Mechanism of Issuing User Certificate in PKI. Based on a serial of PKIX protocols,...
