Post-Quantum Cryptography Architectures for Software-Defined Vehicles

Vehicles produced today will remain operational well past the advent of cryptanalytically relevant quantum computers. AutomotiveQuantum specifies the transition to lattice-based cryptography: replacing vulnerable RSA and ECC with NIST-standardized algorithms across in-vehicle networks and V2X sidelinks.

Protecting Automotive Lifecycles Against Quantum Threats

Adversaries are actively capturing vehicle telematics, OTA updates, and V2X sensor streams, waiting for quantum computers to break classical elliptic curves. AutomotiveQuantum provides hardware-accelerated hybrid key encapsulation and digital signature verification tailored for automotive ECUs.

Core Engineering Areas

• FIPS 203 ML-KEM Automotive Integration — Implementing NIST FIPS 203 (ML-KEM-512/768/1024) to establish quantum-immune session keys between vehicle edge gateways and OEM cloud infrastructures.
• Quantum-Safe V2X Signatures — Adapting NIST FIPS 204 (ML-DSA) and stateful hash-based signatures for low-latency Vehicle-to-Everything direct communication.
• PQC Crypto-Agility Migration — Designing modular security middleware that permits swapping cryptographic algorithms via secure OTA updates as standards evolve.
