摘　　要：针对无线传感器网络存在的虫洞攻击问题,提出了一种基于距离和能量双重约束机制的虫洞攻击检测算法(WAD-DEC)。在邻居发现阶段,提出了距离阈值约束原则,通过限制消息的接收距离来防止虫洞节点建立恶意邻居;在数据传输阶段,提出了加密散列密钥算法对接收的数据进行异常监测。针对异常数据,再用提出的能量阈值约束原则检测虫洞攻击并剔除虫洞节点。在仿真实验中,与AD-PSO、MCPR算法相比,所提算法在时延检测上分别降低了730 ms和440 ms,将错判率最低控制在0.15%以内,检测率最高可达97.5%。结果表明,所提算法能够有效检测出虫洞攻击,在保持高检测精度的同时能够降低检测时延,防止虫洞节点建立恶意虚假邻居,并减少恶意重播消息数量,降低网络能耗,延长网络寿命.Aiming at the wormhole attack problem in the wireless sensor network,a wormhole attack detection algorithm based on the du-al constraints of distance and energy(WADDEC)is proposed.In the neighbor discovery stage,the principle of distance threshold con-straint is proposed,which prevents wormhole nodes from establishing malicious neighbors by limiting the receiving distance of messages.In the data transmission stage,an encrypted hash key algorithm is proposed to monitor the received data abnormally.Energy threshold constraint principle is used to detect the wormhole attack and eliminate the wormhole node for the anomalous data.In the simulation ex-periment,compared with AD-PSO and MCPR algorithms,the delay detection of the proposed algorithm is reduced by 730 ms and 440 ms respectively,the minimum error rate is controlled within 0.15%,and the maximum detection rate is 97.5%.The results show that the algorithm can effectively detect wormhole attacks,reduce the detection delay while maintaining high detection accuracy,prevent wormhole nodes from establishing malicious false neighbors,reduce the number of malicious replay messages,lower network energy con-sumption,and extend network life.
