摘　　要：针对目前基于构件和工作流的集成系统在相关领域的应用,需要一种行之有效的安全访问机制来控制数据访问安全。基于角色的构件与工作流结构,就是把角色分为基本角色组和功能角色组,根据这两种角色的特征,动态地把它们分配到工作流和构件中去控制数据访问安全。Aim at the component, need safety. Flow structure currently the integrated system to be a kind of to go it valid of according to the component and application in related realm that flow and work according to the safety interview mechanism to the work of the role, be is divided into the control data interview basic role set and the function role set to the role, according to these two kinds of characteristics of roles, dynamic state of assign them to the work to flow with go to the control data to visit a safety in the component.

关 键 词：构件 工作流 角色 角色访问控制模型
