Abstract

In order to solve the problem of the lack of security associated with the key and the plaintext image in the color image encryption algorithm, and conditions for the establishment of CAT maps, this paper proposed a color image adaptive encryption algorithm based on improved CAT scrambling system and Henon_Kent chaotic diffusion system. The algorithm firstly used the feature information of plaintext image to generation key. Secondly, it used the improved CAT scrambling system to perform the three-dimensional scrambling of pixel positions. Then it used three chaotic sequences generated by the Henon_Kent chaotic system to spread the pixel gray values of the three channels of RGB respectively. It Repeated the above two steps to ensure that the entropy of the ciphertext image is greater than 7.99. The simulation shows that this algorithm can resist the existing attack methods and has strong encryption performance.
