The configuration item CONFIG_KEYS:

Help text

This option provides support for retaining authentication tokens and access keys in the kernel.

It also includes provision of methods by which such keys might be associated with a process so that network filesystems, encryption support and the like can find them.

Furthermore, a special type of key is available that acts as keyring: a searchable sequence of keys. Each process is equipped with access to five standard keyrings: UID-specific, GID-specific, session, process and thread.

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