An encryption method based on a switching inertia neural network with leakage time lag relates to the field of audio encryption. It solves the problem that the existing encryption method that relies on neural networks adopts a fixed network structure and a static processing mechanism, resulting in the encryption effect being limited by the model performance. The switching inertia neural network with a mixed time-varying delay and leakage time lag constructed by the present invention is used as an audio encryption drive system; and an audio decryption response system is constructed based on the designed synchronization controller and the audio encryption drive system; the subsequent encryption and decryption process is realized under the condition of global exponential synchronization controlled by the synchronization controller. The existence of multiple time lags forms a mixed time-varying delay, and the dynamic behavior of the system is more difficult to predict. The introduction of the time lag inertia weight factor makes the encryption process more complicated, has stronger resistance to randomness and reversibility, and the design of the synchronization controller greatly increases the difficulty of cracking. It is mainly used for the encryption of audio data.
