Abstract

A core network node identifies a non-USIM based authentication procedure to be utilized by a wireless communication device, WCD, being served by the core network node. The node obtains a session key associated with the identified non-USIM based authentication procedure. The node converts the session key associated with the identified non-USIM based authentication procedure to i) a first key, K1, for use by the WCD and a base station serving the WCD to derive an encryption or integrity protection key, Kenc/int, for enabling encryption or integrity protection of a communication between the WCD and the base station or ii) a second key, K2, for use by the WCD and the core network node to derive the first key K1. The node then send i) K1 to the base station or ii) K2 to another core network node that is configured to derive K1 from K2.
