차량용 ECU 하드웨어 보안 모듈 및 EVITA 하드웨어 신뢰점

도메인 및 조널 제어기를 위한 전용 차량용 암호화 실리콘 엔클레이브를 배포하여 무선 펌웨어(FOTA) 업데이트를 보호하고 차량 내 네트워크 게이트웨이를 방어합니다.

AutoHSM Automotive ECU Security Architecture

Cryptographic Enclave: Automotive HSM Enclave — EVITA Full / ISO 26262 ASIL D Core

Hardware Security Nodes & Co-Processors

  • Hardware Secure Boot Engine
  • EVITA Full Crypto Coprocessor
  • Secure Flash & OTA Decryptor
  • Internal Bus Firewall (IDPS)
  • Silicon Monotonic Counter Array

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)

소프트웨어 정의 차량을 위한 하드웨어 신뢰루트

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.
