Evaluation of Mutual Trust during Matchmaking
Mine Altunay, D. Brown, Gregory T. Byrd, Ralph A. Dean · 2005
The authors introduced a new service discovery and matchmaking architecture, layered on top of Globus MDS3, that integrates mutual trust evaluations into the matchmaking process. The architecture adopts a symmetric approach, and checks trust policies of both grid users and resources without requiring policy disclosures. This approach eliminates run-time security failures arising from incompatible user/resource pairs, seamlessly integrates user-side authorization tools with the matchmaking process, and protects naive grid users by allowing a security principal to define policies that control the list of discoverable resources.
