Universal Mobile Telecommunications System (UMTS); LTE; 3G security; Wireless Local Area Network (WLAN) interworking security (V11.4.0; 3GPP TS 33.234 version 11.4.0 Release 11)
The present document specifies the security architecture; trust model and security requirements for the interworking of the 3GPP System and WLAN Access Networks. This specification is not limited to WLAN technologies. It is also valid for other IP based Access Networks that support the same security capabilities towards the interworking system as WLAN does. These security capabilities are addressed in section 4 of this specification. Specifications of the appropriate mechanisms for user and network authentication@ key management@ service authorization@ confidentiality and integrity protection of user and signalling data are also provided.
