Network Smart Card Performing U(SIM) Functionalities in AAA Protocol Architectures

Abstract

Abstract. This paper reviews the way in which the security protocols EAP-SIM/AKA are used in 3G/WLAN network interworking from the point of wiew of the U(SIM). As result, a new AAA protocol architecture is derived from the integration of a Network Smart Card, NSC, that implements U(SIM) functionalities within the scheme. The implementation in a testbed shows the robustness and feasibility of such an architecture.
