Post-Quantum Cryptography Transition Strategies for Automotive Embedded Systems and EV Charging Infrastructures

The rapid progress of quantum computing threatens classical cryptographic schemes (notably RSA and ECC) that are currently used in vehicles, production plants, and connected infrastructures. The automotive industry faces a unique challenge: how to transition to quantum-resistant a.k.a. post-quantum cryptography (PQC) within long product lifecycles, heterogeneous embedded platforms, and complex supply chains. Some ECUs have extremely limited computational resources, while others can support advanced cryptographic algorithms; moreover, vehicles already deployed with classical cryptography must remain secure and updateable throughout service lifetimes that often exceed 15 years. This PhD will explore practical migration strategies to PQC, focusing on hybrid schemes combining classical and PQC approaches, crypto-agility mechanisms enabling smooth algorithm transitions (to switch from classical to PQC or hybrid or from a PQC algorithm to another one if later deemed insecure), onboard security functions that rely on cryptography (secure boot, secure OTA updates, secure debug, secure diagnostic authentication, secure onboard communications, etc.), lightweight implementations for constrained ECUs, physical attacks and countermeasures on PQC in automotive embedded settings.

In addition to onboard aspects, the research will address the adaptation of production line security (e.g., plant Hardware Security Modules, certificate provisioning workflows) and the interoperability of electric vehicle charging stations, which must securely communicate with both vehicles and institutional PKIs. The expected outcome is a framework for managing the secure and cost-efficient introduction of PQC into automotive embedded products and infrastructures, with clear, actionable recommendations for industry adoption.

The research will also consider the evolving landscape of worldwide standards and regulations. Automotive-specific frameworks (e.g., UNECE WP.29 [1], ISO/SAE 21434 [2]) must be reconciled with broader cryptographic guidance from national security agencies and international bodies. This includes standards and recommendations from NIST in the US [3, 3a, 3b], ANSSI and equivalent agencies in the EU [4], and relevant authorities in other regions, where different PQC strategies and timelines are emerging. A key objective is to map regulatory and standardization requirements to automotive use cases, ensuring that proposed migration paths remain globally compliant, interoperable, and future-proof.
