Vehicular Zero-Trust Architecture
VehiclesTrust eliminates perimeter-based automotive assumptions. Every inter-ECU transaction, zonal sensor feed, and cloud API invocation is mutually authenticated and cryptographically attested using hardware security modules (HSMs) and sub-50 microsecond SecOC verification.
Zero-Trust Engine Core Zonal Architecture
Central Controller: Zero-Trust Engine Core — Hardware Security Module (HSM)
Zonal Control Units & TSN Ring
- Secure Boot & Measured Chain of Trust
- IEEE 1609.2 Pseudonym Certificate Authority
- Zonal Microsegmentation Firewall
- Continuous Runtime Memory Attestation
- Cryptographic Token & Key Management Vault
Root of Trust Chains, Sub-Millisecond MAC Verification & WP.29 R155 Compliance
Securing software-defined vehicles demands defense-in-depth across the entire silicon-to-cloud lifecycle. VehiclesTrust orchestrates measured boot chains from cryptographic ROM, isolates compromised zonal controllers using microsegmented firewall policies, and verifies V2X messages against pruned IEEE 1609.2 revocation lists.
Core Engineering Areas
- Hardware-Measured Secure Boot — Anchoring trust in immutable silicon fuses: each bootloader stage measures and cryptographically signs the subsequent binary image before handing over execution.
- Zonal Microsegmentation & SecOC — Implementing AUTOSAR Secure Onboard Communication (SecOC) using AES-128 CMAC and freshness values to prevent message spoofing and replay attacks.
- IEEE 1609.2 Pseudonym PKI — Signing external V2X messages with short-lived pseudonym certificates that rotate every 5 minutes to prevent tracking of citizen travel patterns.
