Study on security aspects of Proximity Based Services (ProSe) in 5G System (5GS) phase 2
The present document studies the security and privacy aspects of proximity based services in 5G system phase 2. It ensures that the security solutions are aligned with the work in SA2 (i.e. TR 23.700-33 [2]), RANs, SA1 (i.e. TS 22.278 [3], TS 22.261 [4], and TS 22.115 [5]) and SA3 (i.e. TS 33.503 [6] and TR 33.870 [7]). The present document covers the following issues:
- Security and privacy key issues, threats and potential requirements of proximity based services in 5G system phase 2.
- Potential security solutions to cover these potential requirements.
Both roaming and non-roaming scenarios are considered.
