The Key Management Service (KMS) protocol as defined in the UEFI 2.3.1 specification is to provides services to generate, store, retrieve, and manage cryptographic keys. The intention is to specify a simple generic protocol that could be used for many implementations.

A driver implementing the protocol may need to provide basic key service that consists of a key store and cryptographic key generation capability. It may connect to an external key server over the network, or to a Hardware Security Module (HSM) attached to the system it runs on, or anything else that is capable of providing the key management service.
