Abstract

Information security has emerged as a key problem in encryption because of the rapid evolution of the internet and networks. Thus, the progress of image encryption techniques is becoming an increasingly serious issue and considerable problem. Small space of the key, encryption-based low confidentiality, low key sensitivity, and easily exploitable existing image encryption techniques integrating chaotic system and DNA computing are purposing the main problems to propose a new encryption technique in this study. In our proposed scheme, a three-dimensional Chen’s map and a one-dimensional Logistic map are employed to construct a double-layer image encryption scheme. In the confusion stage, different scrambling operations related to the original plain image pixels are designed using Chen’s map. A stream pixel scrambling operation related to the plain image is constructed. Then, a block scrambling-based image encryption-related stream pixel scrambled image is designed. In the diffusion stage, two rounds of pixel diffusion are generated related to the confusing image for intra-image diffusion. Chen’s map, logistic map, and DNA computing are employed to construct diffusion operations. A reverse complementary rule is applied to obtain a new form of DNA. A Chen’s map is used to produce a pseudorandom DNA sequence, and then another DNA form is constructed from a reverse pseudorandom DNA sequence. Finally, the XOR operation is performed multiple times to obtain the encrypted image. According to the simulation of experiments and security analysis, this approach extends the key space, has great sensitivity, and is able to withstand various typical attacks. An adequate encryption effect is achieved by the proposed algorithm, which can simultaneously decrease the correlation between adjacent pixels by making it near zero, also the information entropy is increased. The number of pixels changing rate (NPCR) and the unified average change intensity (UACI) both are very near to optimal values.
