5G PKMF: 5G ProSe Key Management Function (5G PKMF) is the logical function handling network related actions required for the key management and the security material for discovery of a 5G ProSe UE-to-Network Relay by a 5G ProSe Remote UE; and for establishing a secure PC5 communication link between a 5G ProSe Remote UE and 5G ProSe UE-to-Network Relay.

PKMF Key Request: A procedure employed by the 5G PKMF of the 5G ProSe Remote UE to request the discovery security materials to the 5G PKMFs of the potential 5G ProSe UE-to-Network Relays from which the 5G ProSe Remote UE gets the relay services; or employed by the 5G PKMF of the 5G ProSe UE-to-Network Relay to request the security materials (e.g. PRUK key) for PC5 communication with the 5G ProSe Remote UE from the 5G PKMF of the 5G ProSe Remote UE.
