Anonymous Communication Scheme for Wireless Mesh Network Based on Network Coding

Abstract

Wireless Mesh Network, holding the features of self-organization, strong scalability, low deploymentcost, is considered to be the most competitive technology for broadband wireless access service.However, the security and privacy issues become the bottleneck for WMN’s rapid popularization.Network coding, which can improve both network throughput and anonymity, is adopted for thecommunication security in WMN recently. However, the related network-coding based anonymouscommunication schemes suffer from the efficiency and security issues. In this paper, an efficientanonymous communication scheme for WMN is proposed, which combines the opportunistic routingprotocol and network coding approach. The global coding vector is protected with the lightweightpermutation encryption mechanism. In addition, the security and performance analysis demonstratethat the proposed scheme can provide strong privacy protection for WMN communication with highnetwork throughput.
