Distributed fiber Bragg grating sensor networks are vulnerable to clear text attacks and need to design active defense security models.A novel active defense security detection method for distributed fiber Bragg grating sensor networks based on fractional domain correlation detection is proposed.Combined with intrusion information detection and feature extraction technology,the active defense security model is designed,and the intrusion information model of distributed fiber Bragg grating sensor network is constructed.The spectrum correlation detection method is used to extract the statistical features of the intrusion information of the distributed fiber grating sensor network,and the optimal matching feature quantity of the distributed fiber Bragg grating sensor network is constructed in the fractional domain.The active defense control of distributed fiber Bragg grating sensor network is realized through fuzzy constraint control method,which improves the security detection ability of clear text attack intrusion.The simulation results show that the proposed method is accurate and the peak output of active defense correlation processing is smooth,which indicates that the anti-interference ability of FBG sensor network intrusion detection is good.The active defense security detection ability of the network is improved.
