Policy Mapper: A Simplified Approach for Administration of Location-based Access Control Policies
An important issue in mobile computing systems is the administration of locationbased access control policies, particularly the mechanism for specification and enforcement of spatial constraints. Simplifying the administration of such policies requires a mechanism that supports both an intuitive and scalable spatial constraint specification and a flexible enforcement architecture. In this paper...

15 صفحه اولNegotiating Access Control Policies Between Autonomous Domains
Autonomous policy domains often need to share resources to accomplish a common task. To do this they must negotiate a common access control policy to the shared resources. We use mathematical techniques from game theory to show that the outcome of such negotiations can often be predicted from the distribution of power among the participants, independent of the actual mechanics of negotiation. W...
متن کاملRewriting-Based Access Control Policies
In this paper we propose a formalization of access control policies based on term rewriting. The state of the system to which policies are enforced is represented as an algebraic term, what allows to model many aspects of the policy environment. Policies are represented as sets of rewrite rules, whose evaluation produces deterministic authorization decisions. We discuss the relation between pro...
