Petrochina Xinjiang Branch Certificate Request Management System Design And Implementation

With the constant application of information systems, the PKI system is playing a more and more role in enterprise's production, operation, and management activities. The user may carry on the application through this system, do the unified management, and grant other registered users the application right by systematic files according to real need. And the system has provided the rigorous access control strategy, and the users without authorization cannot access the specific document, so it can prevent the nonessential information from revelation.This research object of this dissertation is mainly for the realization of data informationization, high-speed and internetization in petroleum system. This software system mainly includes the total eight functional modules, the new application, the frozen applications, the defrosting application, the update application, the cancel application, making up for application, the unlocking application and the system quit. System's digital certificate takes the user driven method to carry on the application management, and newly, all the information system staffs, if they need the digital certificates service, they or the Administrative department may apply the new certificate application to the RA system manager.This platform has some characteristics such as high usability, stability and secure. It can be used by slight modification according to the actual circumstances, and it shows a wide application perspective in enterprises and institutions. In the requirements analysis for this system, this dissertation gives the detailed explanation of overall service as well as the operation flow, and conducts the description to each module function. Moreover, in detail, it presents the system design schedule from the aspects as class structure and database, so it obtains the design class and the database model of the software system. This system has already been put into operation, and the functions and the performances can satisfies the user requirements. It can promote the work efficiency of the petroleum enterprises, with gaining good comments from users, and meeting the requirement of Managers.
