The Study Of Application Of Digital Certificates Based On PKI In Management System Of The Travel Bureau

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.Many country in the world have been studying PKI security mechanism for many years and have formed a integrate set of scheme based on the asymmetrical cryptography and digital signature technology. In this paper we will expound the theory basis, function, application, actuality and foreground of PKI security mechanism.Digital signature and digital certificate are the hard core of the whole PKI and the digital certificate system which manages digital certificate is the hard core of PKI. In this paper we introduce the characteristic,function, frame design ,flow chart and implement of a digital certificate system. At last we introduce the application and flow of the digital certificate system of Shanxi Travel Bureau.
