Hardware Protected Security for Ground Vehicles
RATIONALE
Automotive computer systems are required to establish trustworthiness through device identity, sealing, attestation, data
integrity, and availability. These systems must be resilient to a wide range of attacks that cannot be thwarted through
software-only security mechanisms. A hardware root of trust and the hardware-based security primitives are fundamentally
necessary to satisfy demands of connected and highly or fully automated vehicles. This document provides a
comprehensive view of security mechanisms supported in hardware for automotive use cases, along with best practices for
using such mechanisms.
