Securing military GPS and PNT systems - StoryDecember 02, 2022
Almost every part of our modern economy depends on the Global Positioning System, or GPS. For example, agriculture, construction, mining, rail transportation, and search and rescue all rely on the accurate position, navigation, and timing (PNT) enabled by GPS. An even broader set of industries – communications networks, banking transactions, financial markets, and power grids – rely on GPS for precise time synchronization, to such an extent that most systems would cease working without it. Alternative navigation (ALTNAV) systems can supplement GPS systems in GPS-denied environments using internal clocks and onboard sensors, and those ALTNAV systems should be protected from cyberattacks as well.

Green Hills Software has extended certified multicore support of its INTEGRITY-178 tuMP safety-critical real-time operating system (RTOS) to the 11th-gen Intel Core i7 processor (formerly Tiger Lake). INTEGRITY-178 tuMP is the only RTOS to be part of the certification of a multicore system to DO-178C and CAST-32A multicore requirements.
Zero trust for military embedded systems - StoryFebruary 11, 2022
A zero-trust security posture assumes every user and device is untrusted, even if it is located within the protected perimeter of the local network. The concepts of such perimeterless security have been around for more than a decade, including the “black core” in the architectural vision of the U.S. Department of Defense (DoD) Global Information Grid. Integrators of embedded systems who must have the highest levels of security for such applications as electronic warfare (EW) warning systems can layer higher-level security – such as advanced analytics – atop the embedded computer’s real-time operating system (RTOS) to complete the zero-trust architecture.
