SANTA BARBARA, Calif. Green Hills Software announced that its INTEGRITY-178 Time-Variant Unified Multi-Processing (tuMP) RTOS is being used by Collins Aerospace to meet the NSA's Raise the Bar (RTB) initiative for Cross Domain Solutions (CDS).

Collins is using the INTEGRITY-178 tuMP real-time operating system (RTOS) in the small form-factor, tactical CDS that is being deployed on the U.S. Navy's Tactical Combat Training System Increment II (TCTS II) program and is targeted for the U.S Air Force's P6 Combat Training Systems (P6CTS). 

Raise the Bar is a set of security standards published in 2018 by the National Cross Domain Strategy Management Office (NCDSMO) within the National Security Agency (NSA) to set design and implementation requirements for CDS. RTB standards aim to ensure that CDS systems are at low risk of failing and is designed to combat evolving threats by continually improving CDS effectiveness.

By leveraging the INTEGRITY-178 tuMP operating system, the Collins CDS allows for greater access control, data isolation between applications, resource sanitation, and fault isolation on a multicore processor. Running securely on a multicore processor enables the Collins CDS to increase speeds and support high-assurance information flow policy enforcement from the command centers to the people and platforms at the tactical edge.

With an open systems architecture that is conformant with the Future Airborne Capability Environment (FACE) Technical Standard, TCTS II aims to ensure interoperability between platforms, reduce test time, and increase rapid, affordable deployment of the solution. P6CTS also uses a modular open systems architecture (MOSA) incorporating the FACE Technical Standard to simplify both obsolescence management and future upgrades.
