Coalition-OrBAC: An Agent-Based Access Control Model for Dynamic Coalitions

摘要

In various collaborative environments, autonomous domains form coalitions to achieve shared goals. In most cases, these coalitions are dynamic in nature, as domains leave and new ones join the coalition. Normally, the coalition members have internal access control policies in place. Secure sharing of data requires that the members can exercise fine-grained access control over the shared resources governed by their own security policies. This paper presents an agent-based access control model for dynamic coalitions, which layers coalition management on top of an OrBAC model, and describes our proposition on implementing access control to manage sharing of resources between sector-agnostic monitoring multi-agent system platforms.
