CONFIG_TRUSTED_KEYS: TRUSTED KEYS

General informations

The Linux kernel configuration item CONFIG_TRUSTED_KEYS has multiple definitions:

TRUSTED KEYS found in security/keys/Kconfig

The configuration item CONFIG_TRUSTED_KEYS:

• prompt: TRUSTED KEYS
• type: tristate
• depends on: CONFIG_KEYS
• defined in security/keys/Kconfig
• found in Linux kernels: 3.5–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: masterkey_trusted, masterkey_trusted, trusted, trusted

Help text

This option provides support for creating, sealing, and unsealing keys in the kernel. Trusted keys are random number symmetric keys, generated and sealed by a trust source selected at kernel boot-time. Userspace will only ever see encrypted blobs.

If you are unsure as to whether this is required, answer N.

TRUSTED KEYS found in security/Kconfig

The configuration item CONFIG_TRUSTED_KEYS:

• prompt: TRUSTED KEYS
• type: tristate
• depends on: CONFIG_KEYS && CONFIG_TCG_TPM
• defined in security/Kconfig
• found in Linux kernels: 2.6.38–2.6.39, 3.0–3.4
• modules built: masterkey_trusted, masterkey_trusted, trusted, trusted

Help text

This option provides support for creating, sealing, and unsealing keys in the kernel. Trusted keys are random number symmetric keys, generated and RSA-sealed by the TPM. The TPM only unseals the keys, if the boot PCRs and other criteria match. Userspace will only ever see encrypted blobs.

If you are unsure as to whether this is required, answer N.
