Core engineering and protocols for CPDLC & ACARS Datalink Security.
Historically, CPDLC and ACARS datalinks between aircraft and Air Traffic Control (ATC) operated without encryption or digital authentication. Aviation cybersecurity researchers have demonstrated that malicious ground transmitters can broadcast spoofed altitude clearances or route diversions directly to cockpit multi-function displays.
AvionicsVault integrates into the aircraft Communications Management Unit (CMU), executing an ephemeral hybrid ML-KEM exchange with regional ATC ground stations upon entering new airspace sectors. All subsequent CPDLC clearances and ADS-C position reports are signed and encrypted, ensuring authentic air navigation.
