基于角色和任务的层次对象访问控制模型

An Improved Task-Role-Based Access Control on Hierarchical Object in G-CSCW

    摘要
  • 摘要: 以GIS协同工作应用为背景,探讨了该背景下的访问控制问题,提出了一种基于角色和任务的层次对象访问控制模型,定义了受控对象层次关系和操作类型层次关系,以及基于这两种关系的权限定义规则。实验证明,该模型具有较强的灵活性和适用性,在一定程度上降低了权限定义的复杂度。

     

    Abstract: An improved task-role-based access control model (X-TRBAC) for GIS-based computer supported cooperative work(G-CSCW) systems is presented.Two concepts are introduced: object hierarchy and operation hierarchy.On the basis two concepts,the rules for defining permissions is proposed.The experiments show that the method can simplify the definition of permissions,and it is more applicable for G-CSCW applications.
