Figure 46. Secure update procedure
F.2 SBSFU static keys generation
With KMS middleware integration, SBSFU keys are no more stored in a section under
PCROP protection but inside the KMS code running in the secure enclave as shown in
Figure 47. During SECoreBin compilation stage, prebuild.bat updates SBSFU static
embedded keys inside kms_platf_objects_config.h located in Applications\2_Images
\2_Images SECoreBin\EWARM\ (instead of the se_key.s file update done in the standard
variant).
