摘要
本论文研究整合基于角色与基于任务的访问控制模型及其在电子政务系统中的应用。基于角色的访问控制模型(Role-BasedAccessControl,简称RBAC)缺乏实际应用中工作流程的体现,所以本论文以RBAC为基础,结合了强调工作流程的基于任务的访问控制模型(Task-BasedAccessControl,简称TBAC),提出一种新的整合型访问控制模型,并以其在电子政务系统中的实际应用为例分析说明了该模型解决职责分离、工作顺序和工作相依性问题的具体策略。
The dissertation is dedicated to a new model based on Role-based Acce ss Control (RBAC) and Task-based Access Control (TBAC) and its application in E- government management information system. RBAC is lacking in the w orkflow concept. So the dissertation is dedicated to a new access control model which combines RBAC with TBAC and its application in E-government, and analyzes the policy of the mo del to resolve the problem about the role assignment operation and the r ole control, the workflow order and the workflow dependency.
