Abstract
The proposed next-generation air traffic control system depends
crucially on a surveillance technology called ADS-B.
By 2020, nearly all aircraft flying through U.S. airspace must
carry ADS-B transponders to continuously transmit their precise
real-time location and velocity to ground-based air traffic control
and to other en route aircraft.
Surprisingly, the ADS-B protocol has no built-in security mechanisms,
which renders ADS-B systems vulnerable to a wide range of malicious
attacks.
Herein, we address the question "can cryptography secure ADS-B?"--
in other words, is there a practical and effective cryptographic
solution that can be retrofit to the existing ADS-B system and
enhance the security of this critical aviation technology?
