Architectural Layers & Silicon Defenses

Layer 1: Automotive-Grade Silicon Enclave (AEC-Q100 Grade 0 / Dual-Core Lockstep): Physically isolating vehicular master keys from the host microcontroller core (TriCore/ARM Cortex-R).
Layer 2: Fast Cryptographic Acceleration Core (Hardware AES-128/256-CMAC & SHA-256): Computing message authentication codes and digital signatures for AUTOSAR SecOC in under 15 microseconds.
Layer 3: Secure Boot & Flash Integrity Verification (Hardware Root of Trust / SHA-3 Pipeline): Verifying digital signatures of ECU application firmware before releasing reset lines to main CPU cores.
Layer 4: In-Vehicle Network & Diagnostics Gateway (CAN-FD / Automotive Ethernet 100BASE-T1): Filtering diagnostic sessions (UDS ISO 14229) and authenticating vehicle-to-cloud telemetry.

Cryptographic Telemetry & Compliance: < 12 ms (Secure Boot Flash Verification) | < 15 µs (AUTOSAR SecOC MAC Latency) | ASIL D (Functional Safety Level) | AEC-Q100 (Automotive Silicon Grade 0)

Raízes de Confiança em Hardware para Veículos Definidos por Software

As modern vehicles transition into connected software-defined platforms, Electronic Control Units (ECUs) become exposed to wireless attack surfaces. AutoHSM embeds hardware security modules directly into automotive microcontrollers, enforcing cryptographically signed secure boot, flash integrity protection, and real-time vehicular bus authorization.

Core Engineering Areas

EVITA Full Automotive Architecture — Engineering embedded automotive security modules compliant with EVITA (E-safety Vehicle Intrusion Protected Applications) standards.
Secure Boot & Firmware-Over-the-Air (FOTA) — Protecting vehicular firmware against unauthorized tampering, tuning exploits, and supply chain corruption.
UDS Diagnostic Security & ISO 14229 — Hardening vehicle diagnostic interfaces against unauthorized ECU reprogramming and malicious OBD-II injection.
