Nine-dimensional hyper-chaotic communication encryption circuit

The invention discloses a nine-dimensional hyper-chaotic communication encryption circuit which comprises a signal source, a driving circuit, a response circuit, an encryption circuit and a decryptioncircuit. The encryption circuit encrypts a signal provided by the signal source, the output end of the encryption circuit is connected with the first input end of the decryption circuit, the decryption circuit decrypts the signal encrypted by the encryption circuit, and the output end of the decryption circuit outputs the decrypted signal. The second output end of the driving circuit is connectedwith the second input end of the encryption circuit; a high-dimensional chaotic signal is provided, a signal needing to be encrypted is covered, the second output end of the response circuit is connected with the second input end of the decryption circuit, a high-dimensional signal is output to be used for decryption, the output end of the drive circuit is connected with the input end of the response circuit, and coupling
