Structural diagram 6 of 12. Part of the TPM hub.

Text equivalent

The Full Kernel is three immutable zones: the TPK in full, the TrM identification fields (DOF, DOMAIN, identification, FALSIFIER, BEARS) and the TMS in full (2.1.1). Each zone has a digest; D(TFK) is computed over the three in fixed order (2.5.3). D(TFK) is written into the CAC certificate that assigns the UUID and appended as a BUILD CHAIN line (5.6.4, 5.6.1), and the digest gate matches it before every write and at every CAC (2.5.5).
