In order to improve the encryption capability of key data in wireless networks,an encryption method based on feature selection algorithm for wireless network key data is proposed.The chaotic linear sequence combination design method is used to quantize and encode the key data of the wireless network to obtain the non-linear correlation feature of the key data;the statistical feature detection method is used to extract the characteristics of the key data,and the non-linear correlation feature is used to construct the feature selection model.The fuzzy selection clustering analysis method is used to perform fuzzy combination control on the feature selection model.The key data encryption of the wireless network is based on the combined control result,.The random linear coding and decoding methods are used to complete the encryption and decryption key design of the key data to achieve encryption optimization of key data in the wireless network.Simulation results show that the proposed method has good scrambling and strong anti-attack ability.
