A Research And Implement Of CA System Structure On Private Network

In order to resolve the question of entity's trust relationship in network environment,scientists in the whole world provided a solution that use Public Key Infrastructure (PKI) to realize the distributing and managment of certificate. PKI is a trust relationship system that set by the theory and technology based on public key. It's a universal applicability infrastructure that offer information security service. It' s a module collection such as online authentication,CA authentication,digital certificate,digital signature and secure application component. CA is not only excute unit in PKI but also main parts of PKI. To construct a Certificate Authority is a specific process that design and realize the PKI system structure. The paper first disscusses the foundation theory and general method to realize CA system structure. Finally,it describes the process that realizes a Certificate Authority example in a private network.
