Study and Design of Enterprise Public Security Platform Based on PKI

In order to solve the application security problems in the business operation system in a intensive, uniform and regular manner, a public fundamental platform model based on PKI technology is proposed, and some advanced design concepts like SCA, BPEL, etc. Are introduced for enhancing the reconstructing and reusing of the system. According to the characteristics of PKI system structure, it is expanded as the foundation and realizes the support for WPKI technology. The technical realization of unified user management, unified authority management and unified application security management, as well as the approaches of integrating the peripheral business system are given by analyzing the requirements of general security management of the informatization system. Furthermore, we also proposed methods to further maintain the security and stability of platform operation with technologies like queues, connection pool, etc. Those methods provide a much more uniform solution to the application security problems. The feasibility and effectiveness of the platform in improving the application security problems have been discussed by the illustrations and analysis of the core transaction processing flows of this platform.
