Technologies for Federation and Interoperation of Coalition Networks

When data from two or more coalition members is used in a joint mission, the flow of information over the respective networks must be tightly controlled. Data sent over the networks would be routed through nodes that should enforce policies concerning: what information about each coalition member's assets will be exchanged with other coalition members; who, with what authentication, and under what conditions can access the information, and in what form it can be provided. The authors discuss the requirements of such a policy-enabled federated network, in which any node could be responsible for enforcement of all policies applicable to it and the data that flows through it.
