Languages for Specifying Protection Requirements in Data Base Systems--A Semantic Model.

Abstract

This dissertation develops a model of access control to provide a semantic base for constructs of protection languages at many levels of sophistication, accommodating a wide range of protection policies. The concept of ownership is used for validation of authorizations in the model. Various ownership policies, such as group ownership, subownership, and conditional ownership can be represented. The basic sets of the model are presented and the set of system states is derived from the set of all values of the resources.
