SECURITY: THE KEY TO AFFORDABLE UNMANNED AIRCRAFT SYSTEMS 2 | White Paper EXECUTIVE SUMMARY Cost efficiency and affordability will always be design criteria for the unmanned aircraft system (UAS). There has been much discussion focused on the use of open systems architecture (OSA). One advantage of this approach is to reduce costs. The U.S. Department of Defense (DoD) encourages the use of OSA through its Better Buying Power 3.0 initiatives. UAS designs based on OSA enable the rapid migration of technology across multiple UAS platforms. Open systems architectures will not solve all of the challenges associated with building UASes, however. Security is another factor that has an effect on affordability. In a UAS, the flight control loop extends from the aircraft through the data link to the ground control station. There is also a data link for any payload information. This distributed control and data transfer system introduces security challenges that are not present in traditional manned aircraft. Vulnerabilities exposed by this distributed architecture must be addressed and resolved to minimize the total lifecycle costs of UAS. The cost saving benefits inherent in open systems are negated by a single security breach. Higher cost is often associated with commercial software — however, commercial software with proven security certification evidence helps reduce the total cost of a project and protect the value of missions. Both approaches are valid, and both must account for security vulnerabilities before they can deliver true cost savings. This paper provides an overview of the security considerations for unmanned aircraft, along with a summary of security capabilities delivered by Wind River® technologies such as VxWorks ® , Wind River Linux, and Wind River Simics ® .
