Abstract

The application of the Take-Grant Protection Model to hierarchical protection systems is explored. The proposed model extends the results of Wu and applies the results of Bishop and Snyder to obtain necessary and sufficient conditions for a hierarchical protection graph to be secure. In addition, restrictions on the take and grant rules are developed that ensure the security of all graphs generated by these restricted rules.
