发布时间：2018-10-26 09:39
【摘要】：针对当前防御DoS攻击方法因判定攻击帧合法性条件属性过多所导致DoS防御性能不足的问题,基于粗决策理论,利用粗决策规则方法,建立防御无线DoS攻击的模型,给出基于粗决策规则的防御DoS智能帧过滤算法(802.11w-SFF),并对该方法进行实验分析.802.11w-WiFi设备在攻击速率为250fps的情况下,未使用802.11wSFF方法时,TCP流量变为没有攻击时的16%,UDP丢失率上升为80%;使用802.11w-SFF方法后,802.11wWiFi设备的TCP/UDP数据通信性能没有受到DoS攻击的影响.实验分析说明802.11w-SFF方法应用于移动网络能有效地防御DoS攻击.
[Abstract]:In view of the problem that the current defense DoS attack method has insufficient defense performance due to too many conditional attributes of the legitimacy of the attack frame, based on the rough decision theory and the rough decision rule method, the model of defending the wireless DoS attack is established, which is based on the rough decision theory and the rough decision rule method. An intelligent frame filtering algorithm for defense DoS (802.11w-SFF) based on rough decision rules is presented and analyzed experimentally. When the attack rate of 802.11w-WiFi device is 250fps, the 802.11wSFF method is not used. The loss rate of TCP is increased to 80 when there is no attack. After using the 802.11w-SFF method, the TCP/UDP data communication performance of the 802.11wWiFi device is not affected by the DoS attack. The experimental results show that the 802.11w-SFF method can effectively defend against DoS attacks in mobile networks.
