This effort supported Air Force Research Laboratory (AFRL) to design, architect and build a secure trusted router overlay for military networks based on the realization that many of the infrastructure components that the military depends on for movement of data between military enclaves are commercial end items that may not be configured or manufactured to meet the full qualifications of military mission objectives. Threats to unencumbered movement and assured delivery are the normal physical shortfalls, such as interrupted flow due to broken cables or electrical outages, and the more offensive intentional threats such as malware and subverted infrastructure components. The trusted router effort seeks to remediate this shortfall by providing an overlay onto that infrastructure, with some level of redundancy, and architectural characteristics that allow confidence in the transport, delivery, and content commensurate with the criticality of the traffic.
