“…After a successful Intra-HO Pre-Auth, if MS acquires an authentication with the current TAP again, FIL Re-authentication referred to [13] is immediately invoked for supporting stationary user re-authentication. On the other hand, if the MS roams to other TAP within the same WLAN domain, Intra-HO Pre-Auth will be invoked again.…”

According to the trajectory of MS movement model in Figure 7, MS initially at location ○ 1 must acquire a full authentication via the AP1 resided in WLAN1 domain, and then a re-authentication is invoked with the AP1.…”

“…The contribution of this paper is to propose a fast handover authentication protocol, including Inter-HOPre-Auth and Intra-HO Pre-Auth, which reduces handover authentication delays during Inter-domain HO and Intradomain HO. Actually, the tactics of proposed protocol is extended the concept of Fast Iterative Localized Reauthentication (FIL Re-authentication) implementing in GSM-WLAN Heterogeneous Mobile Networks proposed by S. H. Lin et al in 2010 [10] [11] and based on FIL Re-authentication protocol for UMTS-WLAN Heterogeneous Mobile Networks also proposed by S. H. Lin et al in 2011 as well [12] [13]. When the MS roams across different APs located within the same WLAN domain, WAAA server is appointed to replace HAAA/ HLR/HSS/AuC for authenticating the MS via Intra-HO Pre-Auth prior to performing Intra-domain HO process.…”

“…On the other hand, HAAA server authenticates the MS roaming across different WLAN domains before performing Inter-domain HO process through Inter-HO Pre-Auth. By using similar iteration strategy [13] allows the repeated execution of Inter-HO Pre-Auth/Intra-HO Pre-Auth to reduce the probability of long journey full (re-) authentication occurrence when the MS continues requesting Inter-domain HO/Intra-domain HO. The advantage of integrating with FIL Re-authentication is to provide fast and flexible authentication mechanisms to support stationary user authentication and roaming user authentication.…”

“…[13], standard full authentication delay and reauthentication delay can be expressed as 23*DProp + 16*D Proc and 14*D Prop + 14*D Proc . On the other hand, the authentication delay in FIL Re-authentication, Intra-HO Pre-Auth and Inter-HO Pre-Auth can be expressed as 6*D Prop + 20*D Proc , 11*D Prop + 23*D Proc and 17*D Prop + 23*D Proc , respectively.…”

The demand of ubiquitous communications drives the development of advanced mobile technologies. Meanwhile, recent increases in mobile data usage and the emergence of new IP service applications constitute the motivation to integrate 3GPP cellular mobile systems with broadband WLANs. Since 3GPP and WLAN systems complement each other in terms of infrastructure and network coverage and bandwidth, 3GPP-WLAN Heterogeneous Mobile Networks based on the 3GPP-based Home Network (3GHN) are proposed for meeting the growing demands in high-speed data access on any mobile devices. However, heterogeneous radio access technologies and architectures lead to many interworking issues, such as network transparency, security mechanism, seamless handover, and quality of service. Among of them, security and handover are the major motives to ensure the confidentiality, reliability and continuity of services in 3GPP-WLAN Heterogeneous Mobile Networks. This paper proposes fast handover pre-authentication protocol to reduce the handover authentication latency and authentication signaling overhead during the whole handover session. The proposed protocol supports Intra-Domain Handover Pre-Authentication (Intra-HO Pre-Auth) and Inter-Domain Handover Pre-Authentication (Inter-HO Pre-Auth) for preauthenticating the Mobile User (MS) prior to performing an Inter-domain Handover (Inter-domain HO)/Intra-domain Handover (Intra-domain HO) process. Meanwhile, the reduction in retrieving new Authentication Vector sand key sets from the Home Location Register/Home Subscriber Service/Authentication Center in 3GHN achieves for minimized redundant authentication signaling transactions between 3GPP domains and WLAN domains. In addition, this paper provides simulation results which show that the proposed Intra-HO Pre-Auth achieves 49% handover authentication performance improvement compared to EAP-AKA, and the proposed Inter-HO Pre-Auth achieves 26% handover authentication performance improvement as well.
