  abstract =     "As distributed applications increase in size and
                 complexity, traditional authorization architectures
                 based on a dedicated authorization server become
                 increasingly fragile because this decision point
                 represents a single point of failure and a performance
                 bottleneck. Authorization caching, which enables the
                 reuse of previous authorization decisions, is one
                 technique that has been used to address these
                 challenges. This article introduces and evaluates the
                 mechanisms for authorization ``recycling'' in RBAC
                 enterprise systems. The algorithms that support these
                 mechanisms allow making precise and approximate
                 authorization decisions, thereby masking possible
                 failures of the authorization server and reducing its
                 load. We evaluate these algorithms analytically as well
                 as using simulation and a prototype implementation.",
