A Secure Regional Authentication Layer for Global ADS-B Communications

Automatic Dependent Surveillance-Broadcast (ADS-B) is widely deployed in modern aviation to provide accurate positional data for aircraft. However, ADS-B suffers from vulnerabilities due to the lack of encryption and authentication, making it susceptible to spoofing and tampering attacks. This paper proposes an authentication framework for the ADS-B system using Elliptic Curve Cryptography (ECC) and evaluates the security and performance of this system through both simulation and analytical models. The proposed scheme enhances ADS-B security without compromising realtime performance. Simulation results show the effectiveness of the framework, with a modest increase in computational overhead and significant improvements in data integrity and authentication robustness
