摘要: 以小波法估计Hurst指数为基础,提出了基于提升算法的实时Hurst指数估计法。由NS2仿真实验的结果分析出检测DDoS攻击时流量样本与Hurst指数的关系,得到检测DDoS的实时方法.与传统检测方法相比,该法实时高效。

Abstract: A real-time estimator of Hurst parameter based on the lifting scheme for wavelet transform is presented.Analyzing the relation between network traffic sample and Hurst paremeter on the simulation data of NS2,the method of detecting DDoS attack is proposed.Compared with traditional methods,The proposed approach shows real time and efficiency.
