Abstract : Faced with the constant increase in the number of aircraft circulating in global airspace, the field of ATC (Air Traffic Control) adapts and offers solutions by developing more precise and less expensive surveillance technologies, sometimes to the detriment of cybersecurity issues. The ADS-B protocol (Automatic Dependent Surveillance - Broadcast) perfectly illustrates this point: its objective is to reduce surveillance costs by relying on aircraft to determine their position via the GPS system and to communicate it to the control towers. ADS-B technology thus complements a range of existing technologies (primary or secondary radar) by offering a new way of controlling air traffic. While technologies prior to ADS-B were non-cooperative and required "to watch the sky", the new protocol is cooperative and requires "to listen to the sky." Controllers, who relied on their observations, now trust what planes broadcast by ADS-B messages. In addition to the security issues brought by this new paradigm, the ADS-B protocol has been identified as particularly vulnerable to FDIA (False Data Injection Attack). Due to its lack of encryption and authentication, it allows anyone to issue false surveillance information. FDIA-type attacks therefore aim to alter the overall estimate of the traffic state by combinations of basic operations (add, delete, modify) on ADS-B messages. Faced with these threats, solutions are proposed to strengthen security around ADS-B technology: anomaly detection, data fusion, behavioral analysis, etc.  (...).
