The present document specifies the stage 3 protocol and data model for the Npkmf Service Based Interface. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the 5G PKMF as specified in TS 33.503.
The 5G System stage 2 architecture and procedures are specified in TS 23.501 and TS 23.502.
The Technical Realization of the Service Based Architecture and the Principles and Guidelines for Services Definition are specified in TS 29.500 and TS 29.501.

The 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, for establishing a secure PC5 communication link between a 5G ProSe Remote UE and 5G ProSe UE-to-Network Relay, for discovery of a 5G ProSe UE-to-UE Relay by a 5G ProSe End UE, and for establishing a secure PC5 communication link between a 5G ProSe End UE and a 5G ProSe UE-to-UE Relay (see TS 33.503).
Figure 4-1 provides the reference model (in service based interface representation and in reference point representation), with focus on the 5G PKMF:
The functionalities supported by the 5G PKMF are listed in clause 4.2.1.2 of TS 33.503.
