【摘要】：无线多跳网络(multi-hop wireless networks,MWNs)面临着各种攻击的威胁,尤其是针对路由安全的内部多层攻击和诽谤攻击.信誉机制作为评估节点间信任关系和抵御内部攻击的有效方法,已经被引入MWNs用于保护路由安全.然而,现有成果主要采用分层设计,只考虑单一层次上的攻击,忽略了多层攻击;同时,现有成果还忽略了诽谤攻击和推荐节点的可信性,降低了信誉度评估结果的可靠性.针对上述问题,首先提出基于可靠推荐的跨层动态信誉机制(cross-layer dynamic reputation mechanism,CRM).然后,基于CRM提出了基于推荐保护和跨层信誉机制的安全路由协议(recommendation protection and cross-layer reputation mechanism based secure routing protocol,RPCSR).仿真结果和性能分析表明,RPCSR能够有效抵御内部多层攻击及诽谤攻击,保障路由安全.
[Abstract]:Wireless multi-hop networks (WMNs) face the threat of various attacks, especially internal multi-layer attacks and defamation attacks against routing security. As an effective method to evaluate the trust relationship between nodes and to resist internal attacks, the reputation mechanism has been introduced into MWNs to protect routing security. However, the existing results mainly use hierarchical design, only consider a single level of attack, ignore the multi-layer attacks, at the same time, the existing results also ignore the credibility of defamation attacks and recommendation nodes, and reduce the reliability of reputation evaluation results. To solve the above problems, a cross-layer dynamic reputation mechanism (cross-layer dynamic reputation mechanismCRM) based on reliable recommendation is proposed. Then, a secure routing protocol (recommendation protection and cross-layer reputation mechanism based secure routing protocol RPCSR based on recommendation protection and cross-layer reputation mechanism is proposed. Simulation results and performance analysis show that RPCSR can effectively resist internal multi-layer attacks and slander attacks and ensure routing security.
