Towards a more secure ATC voice communications system

Contradictory to communication safety in the aviation field communication security has received relatively little attention to date, although the threats regarding air traffic security have been rapidly increasing in recent years. Within the project GAMMA (Global ATM Security Management) the German Aerospace Center (DLR) is developing a prototype to support air traffic controllers (ATCO) in detecting intrusions into the air ground voice system and therefore allow subsequent mitigating actions to be conducted.
