Résumé

Quantum Computing raises new threats to C-ITSx. When a cryptographically-relevant Quantum Computer becomes available, classical asymmetric crypto standards might be broken: No more trust in PKI PQC. Benchmark goal is to assess whether PQC algorithms can be used on common hardware without impacting C-ITS standards. Benchmark setup and results: 4 platforms representing low end/high end OBU, RSU, PKI server + Supercop (version 2022-05-06 round3). Main conclusion is try to use Falcon for hybrid signature (with ECDSA) and KYBER. New signature candidates should also be evaluated, but their performance seems too low.
