“…Although a faster re-authentication feature is supported but communications between the VE and HAAA is still prone to high re-authentication delay. We have proposed the LFR protocol [10] that reduces this delay. In LFR, HSS and HAAA delegate the responsibility for reauthentication to the WAAA server.…”

Interworking Universal Mobile Telecommunication Systems (UMTS) and IEEE 802.11 wireless local area networks (WLANs) introduces new challenges in the design of secured and fast vertical handover (VH) protocols. VU operations must not compromise the security of the network. In addition, VH delays must be minimized to maintain the quality of service of the applications running on the User Equipment (UE). Reauthentication is normally required during UMTS-WLAN VU. Existing re-authentication protocols invoked in UMTS-WLAN VH are either inadequately secure or introduces unacceptable delays. This paper proposes couple of re-authentication protocols that reduce re-authentication delays during UMTS-WLAN VHs compared to existing protocols by substantially reducing message signaling. Additionally, they achieve secured key management and mutual authentication between the UE and authentication servers in the 3G Home Network.

“…This may require a handover mechanism that may involve different technologies and providers. Some proposals like AKA [7] for 3GPP-WLAN [8] and 3GPP-WiMax internetworking [9] deal with such interoperability depending on the fact Universal Mobile Telecommunication System (UMTS) is the core network. AKA, as one of the protocols that provide vertical handover has been extensively analyzed using Casper/FDR in [10].…”

Future wireless networks will exploit a variety of wireless technologies to provide ubiquities connectivity to mobile devices in the form of cellular, Wireless Local Area Networks, and femtocells. Inevitably, future wireless networks will be diverse in nature, employing a number of different techniques to associate the hand held devices that are deemed to use the network. Furthermore, mobile users seek for seamless connectivity, while roaming in the midst of different networks. This requires the mobile device and the wireless networks be capable of performing a vertical handover, when the mobile nodes find themselves in the vicinity of a foreign network. Regardless of the technological challenges in terms of security, data integrity and mutual authentication between participating agents remain a significant concern in heterogeneous networks. This paper explores these concerns by examining a number of solutions proposed for vertical handover, and identifies EAP Reauthentication Protocol (ERP) as a technology-independent flexible mechanism for a vertical handover. EAP-ERP satisfies the mobility requirements of future hand held devices while promising the desired security futures. In view of thoroughly exploring EAP-ERP, Casper/FDR has been used in this paper to analyze its security properties under various conditions. The results indicate that despite the initial perception, EAP-ERP lacks mutual authentication between agents, while the integrity of keying material is adequately protected.INDEX TERMS Heterogeneous networks, vertical handover, formal verification, security verification, Casper.

SummaryInterworking third-generation (3G) mobile communications systems and wireless local area networks (WLANs) is advantageous for both service providers and end users. However, securing such interworking architectures is a challenging task. EAP-AKA is the security protocol adopted by 3GPP to achieve authentication in 3G-WLAN interworking architectures. This paper proposes enhancements to EAP-AKA to improve performance and security during re-authentication. A novel protocol named local fast re-authentication (LFR) is proposed to replace the reauthentication protocols in EAP-AKA. The EAP-AKA key hierarchy is restructured to suit the needs of LFR. Evaluations show that LFR is superior to the re-authentication protocols in EAP-AKA in terms of performance and security. LFR has been tested by the automated validation of internet security protocols and applications (AVISPA) security verification tool and proved to be secure.
