Abstract :
We propose a novel approach to provide authenticity and integrity of Automatic Dependent Surveillance-Broadcast (ADS-B) messages. We employ a key-management schema for authentication and rely on a keyed-hashed message authentication code (HMAC) for integrity. Our approach avoids scalability and compatibility issues, as we neither change the packet format nor its size.
