Information Management System And Security Policy--Popedom Module And Authentication Module

In this thesis we mainly discuss the wholely design, detail design and the actural development procedure of two component parts in the Network Information Management System of the Fire-fighting Bureau. After analyzing the difference and connection between the two edition, we apply the widely used idea of authentication center (CA) as our truss of design in the "authentication module" , providing a whole certificate management system to guarantee safe information transfer. In the "popedom module" , which is still used to provide local identity authentication, we mainly disscussed how to divide the power level according to users' needs and how to realize field level access control in database. We also mention the nodus during the design and develop in the last chapter, and give out detailed settle scheme.The two parts in this thesis are mainly served for the information management system of the fire-fighting bureau, but the design and accomplish of the two parts provide us an effective and useful method for safety usage and information security in management information system. The certificate realization method by using OpenSSL, the whole truss of the CA system without special user terminal and the accessing control aimed at fields level in database provide us of reference for future authentication in network information system.
