SEGR: A secure and efficient group roaming scheme for machine to machine communications between 3GPP and WiMAX networks

Abstract

With extensive promising applications, machine to machine (M2M) communications or machine-type communication (MTC) have attached a tremendous interest among mobile network operators and research groups. Supporting multiple MTC devices has been considered as an essential requirement in M2M communications. How to achieve a secure and efficient access authentication for a group of MTC devices during roaming is a challenging issue. In this paper, in order to simultaneously resolve the access security and efficiency in MTC, we propose a secure and efficient group roaming scheme for MTC between 3GPP and WiMAX networks, named SEGR, which is characterized by authenticating all MTC devices in a group simultaneously and speeding up the process of authentication through adopting a novel certificateless aggregate signature technique. Through security analysis, the proposed SEGR can provide robust security, especially overcome the drawback of key escrow in identity-based (ID-based) aggregate signature schemes. In addition, performance evaluations in terms of communication overhead and computation complexity demonstrate that SEGR is more efficient than those traditional schemes.

UPPGHA: Uniform Privacy Preservation Group Handover Authentication Mechanism for mMTC in LTE-A Networks

“…In this section, we firstly analyze the performance of the proposed UPPGHA by comparing it with the current LTE-A handover mechanisms in [7,8] and other related schemes [18][19][20][21] in terms of the signaling cost, the communication cost, and the computational cost. Then, we evaluate the situation when there are some attacks in execution of protocols.…”

“…For the scheme in [18], when the first MD moves into the coverage of the target eNB, the source eNB contacts with the target eNB and transmits all of security context information for the MTC group to the target eNB, and then the target eNB can directly perform the mutual authentication with other group members only with two-handshake without the involvement of the source eNB. For the scheme in [19], taking the advantage of broadcasting and aggregation to design the signaling message, the number of signaling messages for the group is only ( + 9) for the roaming phase. For the scheme in [21], due to the use of proxy mechanism, when on-board UEs hand off the target DeNB, the target DeNB can directly obtain the session key with the UEs without the involvement of the MME.…”

“…Lai et al [19] have proposed a secure and efficient group roaming scheme for MTC between 3GPP and WiMAX networks. By adopting the certificateless aggregate signature technique, the MME/ASN-GW can simultaneously trust a large number of MDs in the handover process and obtains an independent session key with each MD.…”

“…On the signaling cost, we mainly evaluate our scheme by comparing with the schemes [7,8,[18][19][20][21] in terms of the number of signaling messages. According to distinct mobility scenarios, the LTE-A handover mechanisms [7,8] and the GAHAP [20] can be divided into three different goal secrecy of sec md1 kme1, sec enb kme1 %$K {MD1}$ is secret between MD1 and eNB secrecy of sec mdg kme2, sec enb kme2 %$K {MDg}$ is secret between MDg and eNB authentication on s md1 %eNB authenticates MD1 by verifying $S 1$ authentication on s enb1%MD1 authenticates eNB by verifying $S {eNB}$ authentication on s mdg %eNB authenticates MDg by verifying $S {leader}$ authentication on s enb2% MDg authenticates eNB by verifying $S {eNB}$ end goal Algorithm 1: Analysis goals of the model.…”

“…Until now, there are only few research works on the handover authentication process for a large number of devices in wireless networks [18][19][20][21]. 3GPP TR 33.868 [6] has proposed a MD grouping method for congestion avoidance.…”
