Abstract
With the rapid development of communication technology and the Internet, the security of image information has also received more attention. The information characteristics of an image can be described by pixel position and pixel value. Therefore, the encryption algorithm for the image is generally based on these two aspects (Commun Nonlinear Sci Number Simulat 17(7):2969–2977, [1]; Int J Bi-furcation Chaos 7(7):1579–1997, [2]). Using a method alone can easily be cracked by an attacker, so image encryption often combines pixel position scrambling with gray value diffusion. In this paper, chaotic sequences are applied to image data encryption, and pixel position scrambling and gray value diffusion are combined to obtain ciphertext images. And the feedback mechanism is introduced in the diffusion link, so that the ciphertext of each pixel is not only related to the current plaintext, but also relevant to the ciphertext of all the previous pixels, thereby increasing the complexity of the ciphertext.
