ESAT:Extended Security in the Air using TESLA
CoRR(2023)
摘要
The Automatic Dependent Surveillance-Broadcast (ADS-B) is a surveillance
technology that becomes mandatory in many airspaces. It improves safety,
increases efficiency and reduces air traffic congestion by broadcasting
aircraft navigation data. Yet, ADS-B is vulnerable to spoofing attacks as it
lacks mechanisms to ensure the integrity and authenticity of the data being
supplied. None of the existing cryptographic solutions fully meet the backward
compatibility and bandwidth preservation requirements of the standard. Hence,
we propose Extended Security in the Air using TESLA (ESAT), an enhanced
approach that integrates TESLA, phase-overlay modulation techniques and
certificate-based PKI. As a result, entity authentication, data origin
authentication, and data integrity are the security services that ESAT offers.
To assess compliance with the standard, we designed an SDR-based implementation
of ESAT and performed backwards compatibility tests on commercial and general
aviation (GA) ADS-B in receivers. Besides, we calculated the 1090ES band's
activity factor and analyzed the channel occupancy rate according to ITU-R
SM.2256-1 recommendation. Also, we performed a bit error rate analysis of ESAT
messages. The results suggest that ESAT is backward compatible, does not incur
significant communication overhead, and has an error rate that is acceptable
for Eb/No values above 14 dB.
