Abstract

Dynamic coalitions enable autonomous domains to achieve common objectives by sharing resources based on negotiated resource-sharing agreements. A major requirement for administering dynamic coalitions is the availability of a comprehensive set of access control tools. In this paper we discuss the design, implementation, evaluation, and demonstration of such tools. In particular, we have developed tools for negotiating resource-sharing agreements, access policy specification, access review, wholesale and selective distribution and revocation of privileges, and policy decision and enforcement.
