Summary: This paper introduces an abstract reference model, called interaction control (IC), for the governance of large and heterogeneous distributed systems. This model goes well beyond conventional access control, along a number of dimensions. In particular, the IC model has the following characteristics: (1) it is inherently decentralized, and thus scalable even for a wide range of stateful policies; (2) it is very general, and not biased toward any particular type of policies; thus providing a significant realization of the age-old principle of separation of policy from mechanism; and (3) it enables flexible, composition-free, interoperability between different policies.
The IC model, which is an abstraction of a mechanism called law-governed interaction (LGI), has been designed as a minimalist reference model that can be reified into a whole family of potential control mechanisms that may support different types of communication, with different performance requirements and for different application domains.
