  • Description: Abstract With the application and popularization of digital images, the security of images has been paid more and more attention. The bit-level image encryption method has become one of the commonly used methods. It has the characteristic of changing the pixel value while disturbing the position of the pixel point, but at the same time it is accompanied by a higher computational complexity. In order to improve the efficiency of the encryption algorithm, according to the characteristic that the higher 4 of the 8 bit-planes of the grayscale image contain 94.125% of the information of the entire image, the encryption structure of higher 4 bit-planes and lower 4 bit-planes is widely used. But for different images, this characteristic is not accurately applicable. In response to this problem, we design a method of adaptive bit-plane division, which uses mutual information and Jensen-Shannon divergence to measure the amount of information of bit-planes and then divides bit-planes into two parts. The results of bit-plane division are different for different images. Based on this, we propose an image encryption scheme based on adaptive bit-plane division. Compared with the traditional higher 4-bits and lower 4-bits encryption method, this scheme reduces the encryption cost and improves the encryption efficiency. Experimental results show that the proposed scheme can effectively resist the chosen plain-image attacks and has sufficient security.
