“…It is possible to run the UMTS Authentication and Key Agreement (UMTS-AKA) [8,9] protocol over the "GSM Edge Radio Access Network" (GERAN) if the subscriber has a UICC/USIM module instead of the old GSM SIM. The UMTS AKA protocol is defined in 3GPP TS 33.102 [10] and the functions are shown in Fig.…”

Abstract. Many Smart Grid installations rely on General Packet Radio Service (GPRS) for wireless communication in Advanced Metering Infrastructures (AMI). In this paper we describe security functions available in GPRS, explaining authentication and encryption options, and evaluate how suitable it is for use in a Smart Grid environment. We conclude that suitability of GPRS depends on the chosen authentication and encryption functions, and on selecting a reliable and trustworthy mobile network operator.

“…In addition to authenticating the subscriber's identity, cipher and integrity session keys are also generated from the long-term preshared secret key stored in the USIM module and Home Location Register/Authentication Centre (HLR/AuC). A good introduction to the access security in 3G networks is given in Koien (2004); Rose and Koien (2004).…”

Abstract:The Third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks (WLANs) can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined strengths, the integrated networks will provide both wide-area coverage and high-rate data services in hotspots. There are many aspects involved in their interworking, such as mobility, security and Quality of Service (QoS) provisioning. In this paper, we present a survey of most recent interworking mechanisms proposed in the literature, and outline some important open issues to achieve seamless integration.Keywords: 3G/WLAN interworking; tight/loose coupling; mobility management; quality of services; QoS provisioning.
