TL;DR: Experimental results and security analysis show that the proposed encryption scheme for color images based on Deoxyribonucleic acid sequence operations and multiple improved one-dimensional chaotic systems has a good encryption effect and high security.
Abstract: A DNA-based color image encryption method is proposed by using three 1D chaotic systems with excellent performance and easy implementation.The key streams used for encryption are related to both the secret keys and the plain-image.To improve the security and sensitivity, a division-shuffling process is introduced.Transforming the plain-image and the key streams into the DNA matrices randomly can further enhance the security of the cryptosystem.The presented scheme has a good robustness for some common image processing operations and geometric attack. This paper proposes a new encryption scheme for color images based on Deoxyribonucleic acid (DNA) sequence operations and multiple improved one-dimensional (1D) chaotic systems with excellent performance. Firstly, the key streams are generated from three improved 1D chaotic systems by using the secret keys and the plain-image. Transform randomly the key streams and the plain-image into the DNA matrices by the DNA encoding rules, respectively. Secondly, perform the DNA complementary and XOR operations on the DNA matrices to get the scrambled DNA matrices. Thirdly, decompose equally the scrambled DNA matrices into blocks and shuffle these blocks randomly. Finally, implement the DNA XOR and addition operations on the DNA matrices obtained from the previous step and the key streams, and then convert the encrypted DNA matrices into the cipher-image by the DNA decoding rules. Experimental results and security analysis show that the proposed encryption scheme has a good encryption effect and high security. Moreover, it has a strong robustness for the common image processing operations and geometric attack.

Abstract: Based on deoxyribonucleic acid (DNA) coding and two excellent low-dimensional chaotic systems, a new color image cryptosystem is proposed in this paper. The presented image cryptosystem consists of four processes: key streams generation process, DNA sequences confusion process, DNA sequences diffusion process and pixel-level diffusion process. In the first stage, two simple improved chaotic systems and the information entropy of the plain-image are together employed to generate the pseudorandom key streams. Then, the original image is converted into the DNA sequence matrices by the DNA encoding rules, and the binary key streams are used to permute the DNA matrices. The third process performs a row and column diffusion processes on the scrambled DNA matrices by the key streams and DNA XOR operation. Finally, the DNA matrices are transformed into the encrypted image via the DNA decoding rules, and a ciphertext diffusion in crisscross pattern is further adopted to strengthen the security and sensitivity of the cryptosystem. Thus, the resulting cipher-image is obtained. Experimental results and security analysis have demonstrated the excellent performance of our proposed algorithm in image encryption.

Abstract: In this paper, a new robust and lossless color image encryption algorithm is presented based on DNA sequence operation and one-way coupled-map lattices (OCML). The plain-image is firstly decomposed into three gray-level components and we randomly convert them into three DNA matrices by the DNA encoding rules. Then the XOR operation is performed on the DNA matrices for two times. Next, the shuffled DNA matrices are transformed into three gray images according to the DNA decoding rules. Finally, a diffusion process is further applied to change the image pixel’s values by a key stream, and the cipher-image is attained. The key stream generated by OCML is related to the plain-image. Experimental results and security analysis demonstrate that the proposed algorithm has a good encryption effect and can withstand various typical attacks. Furthermore, it is robust against some common image processing operations such as noise adding, cropping, JPEG compression etc.
