Study On The Secure Access Control Based On E-Government

As E-Govment scale development, the E-Govment in the actual work is playing an increasingly important role. Government department's online office has become an inevitable trend, but the current E-Govment security applications were inconclusive. From the network, corporate security threats seriously restricting the development of E-Govment. Access control is an important component of network security, E-Govment in the protection of information integrity, confidentiality and availability play an important role. Therefore, the study of small granularity based on the access control to a certain theoretical and practical significance.The role of the access control based on the classic model of RBAC3 -RBAC96 model communities for the expansion of the model, accompanied by a workflow based on the division of roles methods to make it more suitable for E-Govment application system.The main theses of this research are as follows:1) Proposed a model for the expansion RBAC3 methods to make it more suitable for electronic administrative systems. By the Chief of the electronic access control objectives, a user competence analysis, according to the results of the analysis, targeted for the expansion RBAC3 models. RBAC3 models introduced in workflow, task concept, given the expanded models related concepts, formalization definition, and acts authorized by definition.2) In the course of implementing a system of electronic administrative difficulties and the role of blind users, it is difficult to find and mutually incompatible theories of the expansion model basis, a role-based workflow for the new division. And the realization of practical application of the approach should be relative and specific applications to the development and management, based on access control mechanisms roles greatly simplified application access control and competence management system development and maintenance, to visit more efficient control strategies.3) Administrative systems in the electronic document circulation subsystem design and realization process, the expansion of the use of models designed to expand the access control model of the main functions. Role in the design of a workflow-based approach to the role of division, thus, the better to avoid the division of the roles reversed.4) Pass the test, the certification of such expansion on the basis of RBAC access...
