Posted by John McHaleARLINGTON, Va., 20 Jan. 2011. BAE Systems signed a $3.8 million contract to continue supplying the secure operating system that runs the F-35 Joint Strike Fightermission-planning software. The company's operating system collects data at different security levels and is used by the aircraft's software to develop the mission plan, which includes intelligence, weather, communications, and navigation. That information is then loaded on to the jet for mission execution. When it is complete and the plane has returned, the operating system parses the data according to its security classification. The process, known as a cross domain transfer, occurs within seconds.The BAE Systems XTS-400 Trusted Computer System received a fifth patent for its ability to control information access between processes, file systems objects and devices, complementing existing security and integrity safeguards.
