From 2020, all aircraft must be equipped with ADS-B transponders when entering European and American airspace. Although ADS-B has replaced radar as the core of next-generation ATC, ATC still uses radars to cross-validate surveillance data. We can compare ADS-B signals with radar signals to make sure that flight data is correct, so combining ADS-B and radar surveillance will enhance flight safety. Nevertheless, to give full play to the advantages of ADS-B, it is still necessary to reduce the dependence on radar monitoring. To improve air traffic safety further, we also need to take more measures to prevent security threats to ADS-B communications since ADS-B messages are transmitted on public broadcast channels and are not encrypted or authenticated. Attackers may intercept ADS-B messages or forge ghost aircraft using the low-cost SDR. To minimize the harm caused by these attacks, researchers have suggested many methods, such as authentication, encryption, and location verification.
