The first version of the SBAS Dual Frequency Multi-Constellation (DFMC) standard has been recently finalized. It is foreseen that its extension includes message authentication, to protect avionics from SBAS data spoofing attacks. This paper focuses on the main candidate scheme at the moment, based on the TESLA protocol in the L5-I channel. This paper analyzes which data needs to be used before authentication in order to maintain time to alert. It describes two options, named Authenticate-then-Use and Use-then Authenticate, and analyzes its prospective performance for EGNOS and WAAS. |
