A Unified Framework for Evaluating Data-Dependent Access Control Systems

抄録

We present a flexible framework for evaluating data-dependent access control systems. Based on logical formalism, the framework is general enough to simulate all existing systems. In this paper, we analyze and compare currently available access control systems and demonstrate how they can be simultaneously extended and simplified using our framework. A series of examples and a cross-comparative analysis clearly demonstrate the advantages of our framework over previous methods.
