Based On Pki-ca Security Authentication Server

With the development of Internet and Electronic Commerce, there is a high demand for information safety. In the traditional encryption technique, the distribution of key still hasn't a perfect solution. While PKI technique based public key system resolves it through issuing the certificates by CA (Certification Authority). PKI is a transparent and seamless platform for the network system provided the service of confidentiality, integrity, authentication and non-repudiation, and CA is a necessary and important component of PKI. In this dissertation the author firstly describes PKI modules, function and application, then emphatically discusses CA's certificates issuing and issuance mechanism of revoked certificates and hierarchy of CA. Furthermore analyses the influence impacted to the performance and scalable of the system. Finally presents the realization of CA server for safe certification conforming to PKIX standard.
