摘要
针对移动自组网IEEE 802.11 MAC协议存在的安全问题,提出一种基于攻击集的DDoS攻击方法。该方法可以准确地攻击目标节点,与传统攻击方式相比不表现出冗余的攻击行为,同时降低攻击行为的检测率。利用NS2仿真平台搭建具有动态拓扑的移动自组织网络仿真场景,在此环境下进行DDoS攻击仿真。模拟结果表明,新的DDoS攻击方法可以有效降低移动自组网的通信能力,且攻击节点分布密度加大将增强攻击效果。
According to the security problem of IEEE 802.11 MAC protocol in mobile Ad hoc networks,this paper proposed a novel DDoS attacks based on attack set which could attack target nodes accurately.Compared with the traditional DDoS attacks methods,it didn＇t show any redundant attack behaviors and could be effectively avoid being detected.Further more,built the simulation scenario with dynamic topology by simulation platform NS2,in which DDoS attacks was simulated.The simulation results show that the novel DDoS attacks can reduce the communication ability of networks,and the attack effects will be more obvious as the density of attacking nodes is increasing.
