Abstract
Technologies for systems, methods and computer-readable storage media for reducing the time to complete authentication during inter-technology handovers by reusing security context between 5G and Wi-Fi. Assuming, that the administrative domain for Wi-Fi and 5G match (and belongs to an enterprise for instance), using an already established security context in one technology to do fast authentication in the other technology during handover. Specifically, if UE is on Wi-Fi and handing over to 5G, use its Wi-Fi security context to do fast security setup in 5G, which includes a corresponding method for use when the UE goes from 5G to Wi-Fi.
