This paper proposes a chaotic image encryption method based on the combined scrambling of the improved Josephus transform and the Knight's Tour. First, a chaotic pseudo-random integer sequence is generated and integerized using a memristive chaotic system. Then, the pixel matrix is ​​divided into several small cell pixel matrices. Within each cell pixel matrix, the chaotic pseudo-random integer sequence is used to control the counting starting point, counting period, and counting direction, respectively. Block scrambling is performed using the improved Josephus scrambling algorithm. Subsequently, each cell pixel matrix after the improved Josephus block scrambling is treated as a checkerboard point, and the direction of the Knight's Tour is controlled using the chaotic pseudo-random integer sequence. The image is scrambled using the improved Knight's Tour algorithm and the improved Josephus scrambling algorithm, effectively reducing the correlation between adjacent pixels in the scrambled image and improving the global encryption effect of the image. Finally, the chaotic pseudo-random integer sequence generated and integerized by the memristive chaotic system is used to diffuse the pixels, enhancing the security of the encrypted image.
