Title
No Authentication for Very High Frequency Data Link messages used in CPDLC
Summary
Lack of authentication for Very High Frequency Data Link messages allows rogue ground stations to inject CPDLC messages leading to unexpected or misleading clearances and potential pilot confusion. This type of attack can be carried out remotely over radio frequency.
