摘要
为了可以精准实现光纤网络入侵检测,提出基于马尔可夫判定过程的光纤网络入侵检测方法。通过频域分块技术对光纤网络信号展开信号提纯,利用经验模态分解方法对入侵信号进行初始检测,采用模糊层次分析法确定网络接入行为信用度,对于信用度较高的接入行为直接通过,剩余接入行为则利用马尔可夫判定过程展开判定,由此实现入侵检测。实验结果表明,该方法能够快速、准确检测入侵信号,特别是针对Pording数据集所遭受侵入式窃听行为,检出率高达0.985。在整个实验中,该方法检出率的最小值也可以达到0.920,平均检测误判率、平均检测漏判率的最大值分别为0.01、0.02。这说明该方法显著提升光纤网络的安全性和稳定性,为保障网络安全提供有力的支持。
In order to achieve precise intrusion detection in fiber optic networks,a fiber optic network intrusion detection method based on Markov decision process is proposed.By using frequency domain partitioning technology to purify fiber optic network signals,the empirical mode decomposition method is used for initial detection of intrusion signals,and the fuzzy analytic hierarchy process is used to determine the credibility of network access behavior.For access behaviors with higher credibility,they are directly passed through,while the remaining access behaviors are judged using Markov decision process,thus achieving intrusion detection.The experimental results show that this method can quickly and accurately detect intrusion signals,especially for the intrusion eavesdropping behavior suffered by the lending dataset,with a detection rate of up to 0.985.In the entire experiment,the minimum detection rate of this method can also reach 0.920,and the maximum average detection misjudgment rate and average detection omission rate are 0.01 and 0.02,respectively.This indicates that the method significantly improves the security and stability of fiber optic networks,providing strong support for ensuring network security.
