Automotive cybersecurity: anticipating the transition to post-quantum cryptography

The emergence of quantum computers represents a major challenge for the security of digital systems, particularly in the automotive sector. In response to this development, anticipating the transition to post-quantum cryptography (PQC) has become a strategic priority for vehicle manufacturers and automotive suppliers.

 

As part of the Cybersecurity for Trusted Mobility (CTM) project, IRT SystemX, in collaboration with Oppida, Renault Ampere and Trialog, has conducted research to assess the feasibility and performance of post-quantum cryptography solutions on real-world automotive embedded systems.

 

This research has resulted in a new white paper entitled “Transition to Post-Quantum Cryptography in Automotive Systems: Results from Practical Use Cases”.

 

Through two practical use cases – vehicle-to-infrastructure communications (C-ITS / V2X) and smart charging (Plug & Charge) – this document presents the experiments conducted, the results obtained on embedded hardware, and the key findings to support the industry’s transition towards cryptographic architectures suited to the post-quantum era.

 

In particular, the white paper provides insights into cryptographic hybridisation strategies, measured performance and the implementation requirements for these new solutions.
