Research And Application Of The System Of Privilege Management Platform Based RBAC

In the current society with information technology being developed rapidly, with the fast progress of Internet, big amount of different kinds of information management systems keep emerging. In the area of assuring the safety of the information management systems and the network, RBAC (Role-based access control) system plays an important role. It' s critical to construct a robust permission management access control system to make sure the safety of the management information system security. In the meantime, permission management system is one of the modules which code could be reused to the best degree. However, the current situation is that almost every unit has its own permission management system and invest considerable human and financial resources to it. Hence it dawns on us that we should build a unified, universal permission management model and subsequently put it into practice. This paper is based on the analysis of the status and implementation issues about the role of four RBAC models - RBAC0, RBAC1, RBAC2, RBAC3, summing up their strengths and weaknesses and making improvements to them by proposing new E-RBAC model; It also gives detailed description for the model in the aspects of needs analysis, model structure, and model implementation methods, etc. It proposes the implementation plans as well. Furthermore, it elaborates the model of the design tasks from the design, design agreement, object design, database design, functional design, and testing design aspects, . etc. Finally, the paper briefly explains the way of the implementation of the model and the key algorithm; also it summarizes the features of this system and its prospect in use.
