name: PKMF
full_form: ProSe Key Management Function
context: by a single 5G PKMF, the 5G PKMF takes the role of the 5G PKMF of the 5G ProSe Remote UE and the 5G PKMF of the 5G ProSe UE-to-Network Relay and the inter-5G PKMF message exchanges are not needed. NOTE 2: Steps 0a, 0b, 1a, 1b are performed when the 5G ProSe Remote UE is in coverage. 0a. The 5G ProSe Remote UE gets the 5G PKMF address from the 5G DDNMF of its HPLMN. Alternatively, the 5G ProSe Remote UE may be provisioned with the 5G PKMF address by PCF. If the 5G ProSe Remote UE is provisioned with the 5G PKMF address, the 5G ProSe Remote UE may access the 5G PKMF directly without requesting it from the 5G DDNMF. In case that the 5G ProSe Remote UE cannot access the 5G PKMF using the provisioned 5G PKMF address, the 5G ProSe Remote UE may request the 5G PMKF address to the 5G DDNMF. 0b. The 5G ProSe Remote UE shall establish a secure connection with the 5G PKMF via PC8 reference point. Security for PC8 interface relies on Ua security if GBA specified in TS 33.220 [8] is used (see
description: The ProSe Key Management Function (PKMF) is a network function responsible for managing keys and establishing secure connections for ProSe (Proximity-based Services) communications in the 5G network. It plays a crucial role in enabling secure communication between ProSe Remote UEs and the network.
explanation: The context highlights PKMF's involvement in key management, secure connection establishment, and its interaction with other network functions like DDNMF and PCF. This justifies classifying PKMF as a Network Function, given its specific role within the 5G ProSe architecture.
