Multi-image encryption method based on bit cubes and superpixels

The invention discloses a multi-image encryption method based on bit cubes and superpixels, and belongs to the field of information encryption. Information is easily tampered or leaked in the transmission process, and the multi-image encryption method based on the bit cube and the super pixels is provided for guaranteeing the security of images in the transmission process and the high efficiency of the encryption process. The method adopts a scrambling-diffusion framework. The method comprises the following steps: firstly, combining a plurality of images into a superpixel image; secondly, dividing the bit cube into bit cubes with the same size, and rotating and scrambling the bit cubes by using a chaos sequence; and finally, performing exclusive-or operation on the rows and columns of the multiple pixels respectively. Experimental results and method analysis show that the method can encrypt multiple image contents at the same time, and is good in encryption effect, high in safety and efficient. 一种基于比特立方体和超像素的
