Abstract
Information dissemination is of vital importance in today's
information-centric world. However, controlling the flow of information
across multiple security domains is a problem. Most of the current solu
tions rely on prior knowledge of the users for authorization, which does
not scale well. Also, many information sources have dynamic access control policies, which are hard to satisfy under existing schemes.
In this work, we present Synergy, a general purpose information sharing framework that uses trust negotiation to implement scalable authorization in an open environment. Synergy provides an abstraction for the information sources and consumers to accommodate new trust-aware systems as well as legacy systems.
