| 摘 要： | 针对日益严重的DoS(拒绝服务)网络攻击行为,提出了一种RED(相对熵检测)算法.该算法基于相对熵理论,利用网络流量的自相似特性,通过判断相邻时刻流量之间的相对熵值是否发生突变来进行DoS攻击检测.实验结果表明,与传统的信息熵DoS攻击检测算法相比,该算法具有较高的检测率.

| Abstract: | Based on the theory of relative entropy and the self-similarity of network traff
ic,a Relative Entropy Detection(RED) algorithm is proposed to detect the increas
ingly serious DoS(Denial of Service) attacks,according to judging the changes of
relative entropy v
alues at adjoining times.The experimental results show that the RED algorithm ha
s a higher detection precision compared with information entropy detection algor
ithm. |
