摘　　要：针对移动网络路由冲突导致安全性低的问题,提出基于Hilbert-Huang变换时频分析的移动网络安全冲突检测算法,构建路由冲突下的网络攻击信号模型,对移动网络的入侵信号进行经验模态分解实现谱特征分析和提取,采用HilbertHuang变换对移动网络入侵信号进行高低频组分分解,结合时频分析方法实现路由冲突下的入侵检测,提高网络安全性能。实验分析表明,采用该检测算法进行网络入侵检测的准确性较好,干扰对抗能力较强,是一种有效的移动网络安全策略。In order to solve the low security problem caused by the mobile network routing conflict,the mobile network se?curity conflict detection algorithm based on Hilbert Huang transform time?frequency analysis is proposed. The network attack sig?nal model in routing conflict was constructed. The empirical mode was decomposed for the intrusion signal of the mobile network to analyze and extract the spectrum signature. The Hilbert?Huang transform is used to decompose the mobile network intrusionsignal according to the high and low frequency components. The time frequency analysis method is combined to detect the intru?sion in routing conflict,and improve the network security performance. The experimental analysis results show that the detection algorithm has high accuracy for network intrusion detection and strong anti?interference ability,and is an effective mobile net?work security scheme.
