Based on Hill matrix and dynamic DNA encoding, an image encryption method is proposed. First, this method combines an elliptic curve with a hyper-chaos sequence to fabricate the Hill cipher matrix, and the plaintext image is permuted and encrypted. Second, the dynamic DNA encoding technique is applied to diffuse the gray values of this plaintext image. Finally, hyper-chaos sequences are employed to complete the confusion and diffusion of the image. The experimental results show that the presented method can not only defend against brute-force attacks and statistical attacks but also resist plaintext attacks; in addition, the method has the merits of fast encryption speed, good encryption effects, and easy implementation.

“…Accordingly, some new encryption algorithms are proposed, including DNA computing, chaotic systems, Convolutional Neural Network, fractional transform have been proposed [3,4,5,6]. Chaos system and image encryption have a congenital connection because the chaotic system has special characteristics such as non-periodicity, nonlinearity, pseudo randomness, and extreme sensitivity of initial conditions.…”

“…Since just using a DNA algorithm in image encryption is not enough security that has no robustness against attacks. Therefore, scientists utilize these features with the characteristics of chaotic systems to obtain a more secure image encryption method [3,4,9,10,11,13,14,15,16,17,19].…”

The chaotic systems and DNA operations are used to encrypt images jointly. The fractional Chen Chaotic System is used to generate key DNA images, and the logical map is almost applied to all encryption steps. The values of all the image pixels are first converted from decimal to quaternary, and then represented by DNA sequences. And the DNA computing methods are applied to the diffusion step between the key DNA and the DNA image converted from the plain image. Experiments can prove that the image encryption algorithm proposed by us can meet the requirements of image encryption, and can resist various attack methods, including noise attack, differential attack, etc.
