On Generalized Authorization Problems
S. Schwoon, S. Jha, T. Reps, and S. Stubblebine
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.
