From Classical PKI to Hybrid PQC: A Crypto-Agile Migration Framework for Edge Systems
The "Harvest Now, Decrypt Later" (HNDL) quantum threat is a ticking time bomb for long-lifecycle Software-Defined Vehicles (SDVs), especially with upcoming regulations like the EU Cyber Resilience Act demanding future-proof security. However, hastily replacing classical cryptography with newly standardized Post-Quantum Cryptography (PQC) in resource-constrained ECUs introduces unacceptable safety risks, as these novel algorithms lack decades of real-world vetting. This session bridges the gap between theoretical quantum safety and harsh automotive realities. We present a practical, ISO/SAE 21434-aligned migration blueprint for establishing a sustained Hybrid PQC architecture. Attendees will learn how to implement true defense-in-depth across the vehicle edge, layering the proven reliability of classical ECC with the quantum resistance of NIST's ML-KEM and ML-DSA, while effectively managing critical bottlenecks like ECU memory constraints and in-vehicle network PKI bloat.
From Entropy to Decommissioning: Cryptographic Key Management Strategies Across the Automotive Supp.
From Entropy to Decommissioning: Cryptographic Key Management Strategies Across the Automotive Supply Chain.
Automotive cryptographic key management presents challenges fundamentally different from enterprise IT, driven by heterogeneous ECUs, multi‑tier supply chains, and vehicle lifetimes exceeding two decades. This paper analyzes cryptographic key management as a lifecycle‑coupled system spanning entropy generation, factory provisioning, secure storage, rotation and revocation, and decommissioning. It examines how alignment decisions between OEMs, Tier‑1 suppliers, and silicon vendors shape long‑term security outcomes and how early choices silently constrain or prevent recovery years later. Using real automotive failure modes—such as mis‑provisioning, revocation latency, irreversible trust anchors, and salvage‑yard exposure—the paper shows why many vehicle security incidents originate at production and manifest only in the field. The work emphasizes system‑level, process‑aware design over compliance‑driven or phase‑local controls.
