摘要：In the era of big data, many fields produce massive images every day. To improve the security of image transmission, a multiple-image encryption algorithm based on bit planes and chaos is proposed. Firstly, k images are decomposed into 8k bit planes; secondly, the Chen chaotic system and two-dimensional Logistic map are used to scramble pixel positions of the 5th-8th bit planes of each image; thirdly, the scrambled bit planes and all the 1st-4th bit planes are randomly combined into k scrambled images; finally, to obtain k encrypted images, the exclusive OR operation is performed on the chaotic image and k scrambled images. Experimental results and algorithm analyses show that the proposed algorithm has the advantages of the excellent encryption effect, high encryption efficiency, large key space, key sensitivity, strong ability to resist the statistical attack, the brute-force attack, etc.
