A policy management framework for trusted crossdomain collaboration

Cross-domain collaboration between enterprises needs a trusted execution environment. Policy-based management is a promising and convenient way to construct and manage such an environment. Since management of security and trust policies from collaborating domains has to handle different policies and heterogeneous policy enforcement platforms, an architectural innovation of policy management in this environment is needed. In this paper, a policy management framework is designed and implemented to provide a trusted cross-domain collaboration environment. Merits of this new framework are illustrated through an application in the web services environment.
