The Design And Realization Of CFCA RA

Basing on the encrpytion techniques, PKI (Public Key Infrastructure) provide modules and services for deploying certificate system. The Certificate Authority (CA) is the organization for issuing and managing certificate and is the third part that all believes. The RA (Registration Authority) is the interface of CA to certificate users, and provides service of registering user and managing users.This paper designs a RA system on the FEP of CFCA. It has two versions for Solaris 8 opration system and for Windows NT. RA system use mutiple-thread technology to process the requests from mutiple RA clients. It is of high security by building SPKM linking between RA system and FEP and between RA Server and RA Client. The interface to users is so friendly that this system can be operated simply and can be deployed to a new place easly. Being the Interface of CFCA, the RA system provides digital service with CFCA together.This paper brings forward a kind of proxy system for RA system used in stockjobber. This system can resolve the problem of data sharing between stock system and RA systems, and can simplyfy the flow of stock user applying for digital certificate, provide certificate services that promote the customer's convenience. This system also can be used in other fieldes with little modification.
