Green Hills Software, a company that specializes in high-assurance operating systems, announced this year that its INTEGRITY®-178 Time-Variant Unified Multi-Processing (tuMP™) RTOS for the Xilinx® UltraScale+™ FPGA has been selected by Collins Aerospace for the U.S. Navy's Tactical Combat Training System Increment II (TCTS Inc. II) program. Key factors in the selection of INTEGRITY-178 tuMP were its Multiple Independent Levels of Security (MILS) architecture, its ability to host Multi-Level Security (MLS) applications such as Cross Domain Solutions (CDS), its ability to host a guest OS and legacy applications in a secure virtualized partition, and its conformance to the Future Airborne Capability Environment (FACE™) 3.0 Technical Standard.

Collins Aerospace's TCTS Inc. II solution enables the rapid adaptation of new missions and threats into training as well as joint and coalition interoperability with fourth- and fifth-generation aircraft platforms. The ability for the Navy and Marine Corps to rapidly advance future technology insertions is due to Collins Aerospace's open architecture design and use of industry standards, including alignment with the FACE™ Technical Standard.

The INTEGRITY-178 tuMP high-assurance RTOS is a critical part of a CDS solution with an unequalled security-critical pedigree. The INTEGRITY-178 RTOS is the only commercial operating system ever certified to the Separation Kernel Protection Profile (SKPP) published by the Information Assurance Directorate of the U.S. National Security Agency (NSA). That certification was done by the National Information Assurance Partnership (NIAP) to Common Criteria EAL 6+ “High Robustness.”

The INTEGRITY-178 tuMP RTOS was also the first operating system certified conformant to the latest revision of the FACE Technical Standard, edition 3.0, and it is still the only operating system that meets all of the multicore requirements defined in the FACE 3.0 Technical Standard.
