Stefan Schwoon, Somesh Jha, Thomas Reps, and Stuart Stubblebine. On generalized authorization problems. In Proceedings of the 16th IEEE Computer Security Foundations Workshop (CSFW), pages 202–218. IEEE Computer Society, June 2003.


This paper defines a framework in which one can formalize a variety of authorization and policy issues that arise in access control of shared computing resources. Instantiations of the framework address such issues as privacy, recency, validity, and trust. The paper presents an efficient algorithm for solving all authorization problems in the framework; this approach yields new algorithms for a number of specific authorization problems.
