Enable use of the Trusted Platform Module (TPM) as trusted key
backend. Trusted keys are random number symmetric keys,
which will be generated and RSA-sealed by the TPM.
The TPM only unseals the keys, if the boot PCRs and other
criteria match.

help
Enable use of the Trusted Execution Environment (TEE) as trusted
key backend.

(CAAM) as trusted key backend.
