Key Management

Lifecycle of cryptographic keys from generation through deployment, rotation, and revocation.

Automotive key management covers how keys are generated, provisioned to ECUs at end-of-line, distributed in the field, rotated, escrowed, and revoked when an ECU is decommissioned or compromised. AUTOSAR's KeyM and HSM-backed key stores are the typical implementation surface.
