Design of an extensible microkernel PKI server structure

In the design of PKI certificate server, the application Held, deployment scope and consumer requirements are often considered synthetically in order to select a compatible structure pattern. At the same time, to support future technology development and possible change in system requirements well, the certificate server structure needs have some good characteristics like flexibility and extensibility. This paper puts forward a kind of microkernel PKI server structure. And this structure is simple and easy to employ. It has better extensibility too, compatible to put up a PKI system fast. Because of microkernel particularity, future changes of system requirements have little influence on the performance of server core.
