Airborne Detection of Spoofed ADS-B Reports (Physical-Layer Enhanced Information Fusion)

The objective of this project is to design and demonstrate the feasibility of an innovative physical layer enhanced information fusion approach for real-time detection of air-to-air and ground-to-air spoofed ADS-B reports. The main components of our innovative system include: (1) physical layer based ADS-B spoofing detection; (2) onboard sensors based ADS-B spoofing detection; (3) ground ADS-B spoofing detection; (4) information fusion of multiple ADS-B spoofing detectors. Physical layer based ADS-B spoofing detection and Dempster-Shafer fusion are two core components of our proposed technique. Our algorithm is applicable to all airspaces no matter they are covered by radars/Multilateration or not. The physical layer based method can detect not only the spoofing attack in the air (spoof ADS-B report of aircraft), but also spoofing attack on the ground (spoof the ground station broadcasting). Our physical layer enhanced information fusion system for airborne ADS-B spoofing detection has wide military and commercial applications. BENEFIT: This innovative physical layer enhanced information fusion approach for detection of air-to-air and ground-to-air spoofed ADS-B reports has large potential applications for military and commercial platforms. The primary DoD applications include manned military aircraft, unmanned military aircraft, and helicopter. Our ADS-B spoofing detection technique can protect DOD aircraft from denial of aircraft access attacks via spoofed ADS-B reports. Commercial applications include civil aircraft and UAVs. It can be used directly in the Next Generation Air Transportation Systems (NextGen) to improve the safety, capacity, and efficiency of commercial flights.
