Certificate Management System And Realization

The style of human life and work has been changed greatly by Internet .In our information age, it is imperative to establish a system of identity authentication on network. In this thesis, we study the certificate management system which aims to build network identity authentication systems.First,we introduce some basic cryptography theories such as secret-key cryptography,public-key cryptography and hash algorithm. Second,we give the concepts of X.509 certificate ,CRL(Certificate Revocation List) and certification path, and following this, we give some examples of certificate and authentication architectures. Finally, we present an example of implementation of the certificate and key management system and some application cases of this system. During the period of study, we have constructed a system of certificate management according to the related standards. We have given the description in detail about the whole design scheme of the system,the basic functions and design details of each module in this paper. In the last of part of this paper, we provide application cases of this system.
