Information sharing among collaborating organizations usually occurs in broad, highly dynamic network-based environments, and formally accessing the resources in a secure manner poses a difficult challenge. The mechanisms must be provided to protect the resources from adversaries. The proposed delegation framework addresses the issue of how to advocate selective information sharing among collaborating organizations. We introduce a systematic approach to manage delegated privileges with the specification of delegation and revocation policies using a set of rules. We demonstrate the feasibility of our approach by providing a proof-of-concept implementation. We also briefly discuss several issues from our experiment including future directions.
