Wireless mesh networks (WMNs) upraised as superior technology offering all aspects of services as compared to conventional networks. Due to the absence of centralised authority, WMNs suffers from both external and internal attacks, which decrease the overall performance of WMNs. In this study, the authors proposed an efficient handoff authentication protocol with privacy preservation of nonce and transfer ticket against external attacks during handoff and proposed round trip time (RTT)-based detection protocol to resist against internal attacks in WMNs. For privacy preservation of nonce and transfer ticket, encryption of the nonce and transfer ticket during handoff authentication process was considered. For detection, the calculation of RTT and processing time to identify the malicious nodes forming wormhole link were considered. The proposed work prevents the AODV routing protocol against the wormhole attack in WMNs. The simulation of the proposed work was done using NS-3 simulator, and the experimental results show that the performance of the proposed method prevents WMNs from both external and internal attacks.

基于RTT的无线网状网络检测可保护隐私

与传统网络相比，无线网状网络（WMN）是一种高级技术，可提供服务的所有方面。由于缺乏集中的权限，WMN遭受外部和内部攻击，这会降低WMN的整体性能。在这项研究中，作者提出了一种有效的切换身份验证协议，该协议具有在切换过程中针对外部攻击进行随机数隐私保护和转移票证的安全性，并提出了一种基于往返时间（RTT）的检测协议来抵御WMN中的内部攻击。为了保护现时和转移票据的隐私，考虑了在切换认证过程中对现时和转移票据的加密。为了进行检测，考虑了RTT的计算和处理时间，以识别形成虫洞链接的恶意节点。提出的工作可以防止AODV路由协议抵御WMN中的蠕虫攻击。使用NS-3模拟器对提出的工作进行了仿真，实验结果表明，该方法的性能可以防止WMN受到内部和外部攻击。
