Study on Security Aspects of Enhancement for Proximity-based Services (ProSe) in the 5G System (5GS) phase 3
The present document investigates and identifies the security (including privacy) threats, corresponding security (including privacy) requirements and potential solutions for Proximity Based Services (ProSe) in 5G System (5GS) phase 3, based on the architecture and system level enhancements studied in TR 23.700-03 [1], including
- ProSe multi-hop UE-to-Network Relay (both Layer-2 and Layer-3 Relays).
- ProSe multi-hop UE-to-UE Relay (Layer-3 Relay only).
