Verification of Avionic Security Protocols

Participant : Bruno Blanchet.

security protocols, symbolic model, computational model, verification Within the ANR project AnaStaSec, Bruno Blanchet studied an air-ground avionic security protocol, the ARINC823 public key protocol  [24]. He verified this protocol both in the symbolic model of cryptography, using ProVerif, and in the computational model, using CryptoVerif. While this study confirmed the main security properties of the protocol (entity and message authentication, secrecy), he found several weaknesses and imprecisions in the standard. He proposed fixes for these problems. He delivered this work to the ANR and he plans to submit it for publication next year.
