Security for digital aeronautical communications has been considered in few works. The Aeronautical Radio Inc. (ARINC) transport communications provider introduced the Aircraft Communications Addressing and Reporting System (ACARS) to allow data messages exchange between the air and the ground. Given the fact that many eavesdropping attacks have been done on the system, a new and secure version was proposed to avoid this kind of issues (ACARS Message Security – AMS) [7]. AMS is a good security framework to secure ACARS message but the technology became obsolete as soon as ATN /IPS has been defined as the future standard for ATS and AOC data-based services.
