A chaos-based encryption algorithm for industrial design images

The focus of this paper is the security of industrial design images. An encryption algorithm, based on the Logistic and the Henon maps, is proposed. The algorithm aims to ensure the security of industrial design images, and uses chaotic iteration to generate the encryption keys, and then carries out the XOR and cyclic shift operations on the plain text to change the values of image pixels. The algorithm enhances the security of the algorithm in that secret keys in the encryption process are not only associated with the chaotic maps, but also to intermediate cipher text. In experiments, the corresponding results showed the proposed method is a promising scheme for image encryption in terms of robustness.
