车规级 ECU 硬件安全模块与 EVITA 汽车信任根

在整车域控制器与区域控制器 (Zonal Controller) 中全面部署专用汽车级硬件加密安全隔离区，确保空中软件升级 (FOTA) 绝对防篡改，并铸就坚固的车载以太网/CAN 通信网关防御屏障。

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)

面向软件定义汽车的硬件信任根

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.
