CANCryptography: Sécurisation des Réseaux de Bord, SecOC AUTOSAR et Calculateurs Post-Quantiques

CANCryptography conçoit des protocoles d'authentification cryptographique post-quantiques pour les réseaux CAN et CAN FD, l'Ethernet automobile et la communication sécurisée AUTOSAR (SecOC), garantissant la sûreté de fonctionnement automobile à l'ère post-quantique.

Central System: SecOC Quantum Core - CAN FD Bus Guard

Cryptographic Nodes

  • Truncated MAC
  • Freshness Counter
  • SecOC Module
  • Gateway ECU
  • Ethernet Backbone

Architectural Layers & Protocols

  • Physical Bus & Arbitration Layer (ISO 11898-1 CAN FD 5 Mbps Bus & 100BASE-T1 Automotive Ethernet): Transmitting critical sensor and actuator telemetry with deterministic bus timing and fault tolerance
  • SecOC Truncated Post-Quantum MAC Layer (Lattice-Derived Symmetric Key Message Authentication Codes): Injecting cryptographic message authentication into CAN FD frames without exceeding 64-byte payload caps
  • Freshness Value Management (FVM) (Trip Counter & Monotonic Timestamp Synchronization): Eliminating replay attacks and message re-ordering across power cycles and vehicle sleep states
  • Automotive Central Gateway & HSM Bridge (EVITA Full / High Hardware Security Module Partitioning): Translating post-quantum TLS 1.3 packets from telematics into SecOC frames on internal vehicle buses

Key Metrics: 64 Bytes (Max CAN FD Frame Payload) | <50 µs (Authentication Verification Time) | ISO 21434 (Automotive Security Standard) | Zero-Loss (Bus Arbitration Reliability)

Protéger le système nerveux du véhicule autonome contre la menace quantique

Vehicles produced today will remain on public roads well past 2040, within the window of operational quantum computing. Compromising in-vehicle bus messages allows malicious adversaries to override steering, throttle, and braking commands. CANCryptography hardens automotive transport.
