BlueField-3 Measurements | Device Attestation and CoRIM-based Reference Measurement Sharing

The measurement specification for all the indexes listed in the table below is: 0x01 (DMTF).

The CoRIM files include the same measurement block definition encoded in base64 format, as outlined below. If the table indicates "Yes" under the "Part of CoRIM" column, the index is included in the CoRIM file; otherwise, it is excluded.
