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.
