Abstract
In this work, we integrated three quantum-safe digital signature algorithms, CRYSTALS-Dilithium, FALCON and Rainbow, into notification messages used in intelligent transport systems. We evaluated the performance of the algorithms by measuring the time required to sign and verify messages, as well as the size of the signed messages, and compared the quantum-safe options to the elliptic curves currently accepted by the standards. Our results show that quantum-safe digital signature algorithms could be used for signing notification messages in intelligent transport systems, with only moderate changes to performance. The results also provide an evaluation of three quantum-safe digital signature algorithms’ suitability for this purpose, thus helping to choose suitable algorithms when migrating intelligent transport systems towards quantum resistance.
