Hardware TPM 2.0 Security Enclaves for Software-Defined Vehicles

AutomotiveTPM defines the integration of Trusted Platform Module (TPM 2.0) silicon into central automotive compute and zonal nodes: securing root keys in tamper-resistant hardware, binding software states to PCRs, and enabling verifiable cryptographic remote attestation.

Why Software-Only Key Storage Fails Vehicle Audits

Storing cryptographic private keys in general-purpose flash leaves connected vehicles vulnerable to voltage glitching, bus probing, and cold-boot attacks. Dedicated automotive TPM 2.0 chips provide active mesh shields, zeroization triggers, and cryptographic isolation.

Core Engineering Areas

• Measured Boot & PCR Sealing — Extending Platform Configuration Registers (PCRs) with cryptographic hashes of boot stages, ensuring decryption keys are released only if every software component is unmodified.
• Remote Platform Attestation — Generating TPM quotes signed by the hardware Endorsement Key, enabling OEM cloud servers to cryptographically prove vehicle integrity before deploying firmware.
• Tamper Detection & Zeroization — Detecting physical intrusion attempts—including drill holes, laser attacks, and casing removal—and triggering hardware zeroization lines.
