IMAGE ENCRYPTION TECHNOLOGY BASED ON IMPROVED CHAOTIC SPARROW SEARCH ALGORITHM S-BOX AND NEURON CIRCUIT
The current image encryption algorithm using S-box structure is too simple and is easy to be cracked.The chaotic map(MPSNC)obtained by the improved pulse-coupled spike neuron circuit was used to optimize the CSSA algorithm.A new chaotic S-box was designed by combining MPSNC mapping with the improved CSSA.An image encryption algorithm was constructed based on MPSNC mapping and new chaotic S-box.In order to increase the change of S-box,S8 transform was performed on it.The chaotic sequence was generated by iterative chaotic mapping.The chaotic sequence and S8S box were used to diffuse and scramble the image,and the encrypted image was obtained.Experimental results show that the encryption algorithm has rich parameters and high complexity.Due to the application of S-box,the nonlinearity of the algorithm is improved,and the algorithm has good performance,which is suitable for image encryption.
