help
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.

bool "TEE-based trusted keys"
depends on TEE >= TRUSTED_KEYS
default y
help
Enable use of the Trusted Execution Environment (TEE) as trusted
key backend.
