Secure Boot
A cybersecurity process ensuring only verified software runs on vehicle ECUs.
Secure boot prevents unauthorized or tampered firmware from loading during startup. It verifies each software layer using cryptographic signatures stored in secure hardware. If verification fails, the ECU refuses to boot, preventing malware execution. This technique ensures integrity from the factory through the vehicle's lifetime. Combined with encryption and secure updates, it forms the foundation of trusted automotive computing.
