Study on authentication and key management for applications based on 3GPP credential in 5G
The present document specifies key issues, derived requirements and potential solutions to support authentication and key management aspects for applications and 3GPP services based on 3GPP credentials in 5G, including the IoT use case. It analyses issues and requirements for:
- providing authentication and key management procedures to applications and 3GPP services in 5G scenarios which allow the UE to securely exchange data with an application server;
- decoupling these procedures from the transport protocol, in order to allow for the adaption to different application layer protocols.
The present document takes into account new solutions as well as potential adaptations to existing ones such as GBA described in TS 33.220 and BEST described in TS 33.163, in order to support the above mentioned requirements with procedures and protocols defined in SBA.
