摘    要:从主体和客体两方面探讨了访问控制问题,提出了一种基于角色和任务的访问控制模型。该模型不但考虑了访问控制的主体(用户/角色),以及访问控制所处的环境(静态/动态),而且引入受控对象层次和操作类型层次概念,并定义相应的处理规则进行权限定义,使权限定义变得更加简单明了。

关 键 词:安全约束  RTBAC  权限管理

Abstract:An improved task-role access control model was presented. Subject(user/role) and condition( dynamic/ static) were caculated in this model. Two concepts were introduced :object hierarchy and operation hierarchy. On the basis of two concepts , the rules for defining permissions was proposed. The experiments showed that the method could simplify the definition of permissions.
Keywords:RTBAC
