Radio Frequency fingerprinting of aircraft ADS-B transmitters? Boffins reckon they've cracked it

A group of academics reckon they've found a way to uniquely fingerprint aeroplanes’ Automatic Dependent Surveillance-Broadcast (ADS-B) tracking transmitters – though an aviation infosec boffin says more research is needed to verify the new technique.


In a paper titled “Real-World ADS-B signal recognition based on Radio Frequency Fingerprinting,” three Chinese researchers describe what they said was a method of identifying unique transmitters fitted to aircraft – regardless of what identity code the equipment is broadcasting.


“We propose and design a novel RFF recognition scheme based on Contour Stellar Images and deep learning. We designed an ADS-B original signal capture and labelling method and verified this method by using a 1090MHz baseband signal collected by RTL-SDR, collecting signals from a total of 5 aircraft,” wrote the researchers in their paper ..
