The objective of this R&D is to demonstrate the feasibility of producing and using, a family of inexpensive, trusted interface devices to support controlled, secure transfer of data between C3I systems accredited to operate in dedicated or system high mode at unequal classification levels or other mandatory control categories (e.g. Sci compartments, foreign releasability controls, and other special access designations). With this approach, no new hardware or software security requirements are imposed on the primary mission ADP components. All access control policy requirements for the interconnections are enforced by the trusted interconnecting devices. The PHASE I effort will show how these relatively expensive generic devices can be combined with existing ADP components (both stand alone and networked) to support controlled, reliable, and secure sharing of information across security level/category boundaries. Architectures, concepts, preliminary specifications and designs will be produced for a baseline family of generic, trusted interconnect devices (TIDS).
