Post-Quantum Cryptography Integration in CAN FDx Automotive Networks: Security and Performance Evaluation.

The rise of quantum computing threatens traditional cryptographic systems such as RSA and ECC, which can be broken by quantum algorithms. This poses significant risks for the automotive industry, where in-vehicle communication networks must ensure both low latency and high data integrity. Modern vehicles rely on Controller Area Network Flexible Data-rate (CAN FD) and its full-duplex extension (CAN FDx), making them critical for implementing quantum-resilient solutions.
This project addresses the gap between theoretical advances in post-quantum cryptography (PQC) and their experimental validation in real-time vehicular environments. It aims to design, implement, and evaluate PQC algorithms—Kyber, Dilithium, Ascon, and Ring-LWE derivatives—within CAN FDx networks. By testing these algorithms on embedded platforms, the project will generate quantitative data on timing, performance, and security, supporting both industrial adoption and standardization efforts.
The work will deliver practical, quantum-resilient communication mechanisms for CAN FDx networks that maintain real-time constraints while ensuring secure message exchange among electronic control units (ECUs). It also strengthens collaboration between Brazilian and Canadian research groups in secure embedded architectures and post-quantum automotive systems, advancing the development of trustworthy, high-performance vehicular communication frameworks for the quantum era.
