基于角色访问控制在工作流管理系统中的应用研究

Study on the Application of Role-based Access Control in Workflow Management System

针对实际应用的需求和工作流管理系统的特点 ,提出了一个适合工作流管理系统的基于角色的授权控制模型 ,并将该模型应用到基于过程分解的工作流模型中 ,从而得到一个具有基于角色的访问控制与授权机制的工作流管理系统 .对其中的静态以及动态约束问题进行了分析 .

Taking the characteristics of WFMS (workflow management system) and the requirement of real application into consideration, this paper presents a role based access control model, which is suitable to workflow management systems, and applies it to the process discomposing based workflow model. The problem of the static and dynamic constraints in role based access control and authorization is introduced in some detail. Finally, it analyzes the architecture and implementation of a WFMS enactment system which supports RBAC.
