Content for TR 33.847 Word version: 17.1.0
1 Scope p. 11
The present document studies the security and privacy aspects of proximity based services (including public safety and commercial proximity services) in the 5G system. It ensures that the security solutions are aligned with the work in TR 23.752, TS 22.278 and TS 22.261. The present document covers the following issues:
- Security and privacy key issues, threats and potential requirements of proximity based services in 5G system.
- Potential security solutions to cover these potential requirements.
2 References p. 11
