对多分簇网络攻击伪装数据时间延迟控制,延迟攻击时间,为实现攻击伪装数据的准确检测提供时间差.传统方法采用均匀分布控制方法实现对攻击数据的时间延迟,当攻击数据具有非均匀和非线性特性时控制效果较差.提出一种基于独立自相成分分析的多分簇网络攻击伪装数据时间延迟控制算法.首先构建一个基于多分簇框架的网络攻击模型,在时间-尺度二维平面上,采用一个酉正性特征分解模型表示出待检测信号的时频向量,使用不同的尺度观察信号攻击过程中分布的位置和尺度参数,得到检测问题的最佳检测器为副本相关积分检测器,最大限度对各独立变量进行自相成分表征,得到伪装数据的时间延迟控制系统.仿真结果表明,该算法能有效实现网络攻击伪装数据的时间延迟,提高检测性能,保证网络安全.

The delay control for multi cluster network attack the disguised data delay time, attack time, to achieve accurate detection of attack of camouflage data provide the time difference. The traditional method is using the control method to re-alize the delay time of attack data uniform distribution, when the attack data with inhomogeneous and nonlinear characteris-tics is poor control. Proposed one kind based on independent component analysis in multi phase clustering network attack the disguised data time delay control algorithm. First, build a network attack model based on multi clustering framework, in the time scale of two-dimensional plane, decomposition model show time frequency vector signal to be detected by a uni-tary characteristic, position and size distribution using different scales of observation signal attacking process parameters, the optimum detector to obtain the detection problem for the replica correlation integration detector, the maximum self phase composition characterization of each of the independent variables, get the disguised data time delay control system. The simulation results show that the algorithm can effectively test the network attack of camouflage data time delay, im-prove the detection performance, network security.
