ActiveCN115623139Bimprove securityclose relationshipImage watermarkingSecuring communication by chaotic signalsAlgorithmCiphertext
A chaotic image encryption method based on three-dimensional Rubik's cube scrambling and diffusion, the method converts the pixels in the plaintext image into a three-dimensional Rubik's cube pixel matrix through a preprocessing operation mode and generates a corresponding key according to the size of the plaintext image and the initial parameters of the non-equilibrium point chaotic system; at the same time, the chaotic sequence generated by the non-equilibrium point chaotic system is converted into a three-dimensional Rubik's cube chaotic matrix with the same size as the three-dimensional Rubik's cube pixel matrix; according to the key and the three-dimensional Rubik's cube chaotic matrix, the three-dimensional Rubik's cube scrambling and diffusion operation of the three-dimensional Rubik's cube pixel matrix is completed in the three-dimensional space; after three rounds of three-dimensional Rubik's cube scrambling and diffusion operations, a ciphertext image is obtained. The method of the invention can achieve a good encryption effect and effectively protect the information security of the image.
