We study the specification of access control policy in large-scale distributed systems. Our work on real-world policies has shown that standard policy idioms such as role hierarc...
A multi-agent marketplace, MAGNET (Multi AGent Negotiation Testbed), is a promising solution to conduct online combinatorial auctions. The trust model of MAGNET is somewhat diffe...
Distributed Role-Based Access Control (dRBAC) is a scalable, decentralized trust-management and accesscontrol mechanism for systems that span multiple administrative domains. dRBA...
