Secure Management of Distributed Collaboration Systems
نویسندگان
چکیده
Our goal is to construct secure distributed collaboration systems by coupling their high-level specifications with a policy-driven middleware. This paper addresses three problems related to decentralized management of collaboration systems by a middleware. To correctly enforce security and coordination policies, the middleware determines which nodes can be trusted for enforcing policies related to different aspects of a collaboration system. Secondly, the middleware ensures consistency in evaluation of coordination constraints. Lastly, security and integrity of event communication is addressed. Moreover, we present the steps for building collaboration systems using our middleware.

The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...
