Firmware Verification

D3-FV
D3-FV (Firmware Verification)

Definition

Cryptographically verifying firmware integrity.

How it works

Cryptographic hash values are computed for system and peripheral firmware. The hash values are compared against precomputed hash values for the identified firmware. A hash value mismatch may indicate that the firmware may have been tampered with or updated with a non-current release indicating a misconfiguration for the system.

Considerations

  • Requires cryptographically computed hash values of firmware
  • Requires storage of precomputed firmware hash values
