Abstract
A method by a core network node of a core network of a wireless communication system for authenticating a user equipment, UE, to the core network includes receiving a first authentication request to authenticate the UE to the core network, determining that the UE should be authenticated by an external authentication entity that is external to the wireless communication system, transmitting a second authentication request to the external authentication entity, the second authentication request identifying the UE, receiving an authentication response from the external authentication entity verifying authenticity of the UE, the authentication response including a master key, and deriving a first key for securing communications with the UE from the master key.
