摘要 用角色而不是个体作为存取控制的粒度单位有许多优点 ,这些优点在层次 RBAC(偏序 )中得到进一步体现 ,NTree是定义这种偏序既自然又系统的方法 .本文介绍了偏序的超矩阵表示及相应的 NTree判别和近似表示方法 . There are many benefits for providing access control with roles of users rather than individuals as the unit of granularity .The benefits are enhanced if the roles are organized in a hierarchy (or partial order). In this paper, the super matrix representation of a hierarchy ,and the recognition and approximation of NTree are introduced.
