“…Compromising PMK enables an attacker to launch ''false base station'' attacks on a legitimate MS during R3HO [24], thus breaches S3. Non-compliance with S2 in the optional HHO was also shown in [20].…”

“…In MDHO and FBSS, the MS registers and maintains a list of potential TBSs and is required to share its security context with them. MDHO and FBSS do not satisfy security requirements S1-S4, introduce additional traffic in the network and require more complex hardware [20][21][22]. Due to these problems, we are only considering HHOs in this paper.…”

“…Few papers target HO improvements based on optimizing the authentication procedure [20,23,30]. Hur et al [20] proposed fast HO protocols achieved by pre-distributing PMK and AK keys to target BSs prior to a HO.…”

Interworking UMTS and WiMAX networks offers global roaming and cost effective broadband wireless Internet access. Designing efficient Intra and Inter WiMAX handovers in the interworking architecture is a challenging problem. Handovers must be instantaneous and secure at the same time. We attempt to solve this problem by designing Intra and Inter WiMAX handover protocols which are capable of operating in the UMTS-WiMAX interworking architecture and perform mutual pre-authentication between the mobile station and the target network prior to handover. Due to the pre-authentication procedure, our proposed handover protocols outperform standard handover protocols by dispatching fewer handover signaling messages, experiencing less handover delay and preserving computation resources of critical nodes in the interworking architecture. Furthermore, our proposed handover protocols meet essential security requirements and defend against common attacks affecting handover protocols.

“…In this Figure, the result of EAP authentication protocol is MSK. Then both the MS and BS make a Pairwise Master Key (PMK) by removing some bits of the MSK using a number of functions such as Dot16KDF [12], and also they generate an Authorization Key (AK) from the PMK. After making the AK, the BS and MS will establish the Key Encryption Key (KEK) from the AK.…”

“…In this way, for each MS i there are two sets of keys as follows: Figure 7 shows the revised version of ELAPSE. Here, a node i in subgroup 2 has three keys SGKEK 1234, SGKEK 12 and SGKEK 2 as well as a two-key set SGFSet i 2 and SGBSet i 2 . Upon member join or leave event, the rekeying algorithm updates SGKEKs and GTEK, but there is no change in SGFSet and SGBSet sets.…”
