The increasing demand for secure interactions between network domains brings in new challenges to access control technologies. In this paper we design an access control framework which provides a multilevel mapping method between hierarchical access control structures for achieving multilevel security protection in cross-domain networks. Hierarchical access control structures ensure rigorous multilevel...

So to make sure the authorization of multilevel security access control can be legally enforced, the access control policies must be correct and complete. Based on the implicit hierarchical relations between subjects and objects in multilevel security access control systems, this paper gives...
