A new color image encryption technique using DNA computing and Chaos-based substitution box

Abstract

In many cases, images contain sensitive information and patterns that require secure processing to avoid risk. It can be accessed by unauthorized users who can illegally exploit them to threaten the safety of people’s life and property. Protecting the privacies of the images has quickly become one of the biggest obstacles that prevent further exploration of image data. In this paper, we propose a novel privacy-preserving scheme to protect sensitive information within images. The proposed approach combines deoxyribonucleic acid (DNA) sequencing code, Arnold transformation (AT), and a chaotic dynamical system to construct an initial S-box. Various tests have been conducted to validate the randomness of this newly constructed S-box. These tests include National Institute of Standards and Technology (NIST) analysis, histogram analysis (HA), nonlinearity analysis (NL), strict avalanche criterion (SAC), bit independence criterion (BIC), bit independence criterion strict avalanche criterion (BIC-SAC), bit independence criterion nonlinearity (BIC-NL), equiprobable input/output XOR distribution, and linear approximation probability (LP). The proposed scheme possesses higher security wit NL = 103.75, SAC ≈ 0.5 and LP = 0.1560. Other tests such as BIC-SAC and BIC-NL calculated values are 0.4960 and 112.35, respectively. The results show that the proposed scheme has a strong ability to resist many attacks. Furthermore, the achieved results are compared to existing state-of-the-art methods. The comparison results further demonstrate the effectiveness of the proposed algorithm.

A Novel Virtual Optical Image Encryption Scheme Created by Combining Chaotic S-Box with Double Random Phase Encoding

“…The ideal value of NPCR is 99.6093%, and the ideal value of UACI is 33.4635% [ 61 ]. The NPCR and UACI values of ciphertexts of different images obtained by our scheme are shown in Table 6 .…”

“…Recently, some image encryption algorithms using chaotic S-Boxes have been proposed [ 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ]. For example, Zhang et al developed an efficient chaotic image encryption scheme using alternate circular S-boxes with the chaotic S-boxes being produced by the Chen chaotic system [ 56 ].…”

“…Wang et al developed a novel image encryption scheme employing a spatiotemporal chaos-based dynamic S-box and random blocks [ 60 ]. This S-box was constructed using one-dimensional (1-D) and 2-D chaos mapping and DNA sequencing [ 61 ]. Simulation results showed that the proposed algorithm had the ability to resist many kinds of attacks.…”

VLSI Implementation of Optimized 2D SIMM Chaotic Map for Image Encryption

“…Chaotic Shift Transform (CST) is proposed to change the position of image pixel efficiently whereas the row and column substitutions are applied to scramble the pixel values simultaneously. The optimization algorithm is proposed to resolve the constrained and unconstrained optimization problems for encryption [2]. This algorithm is based on the concept that the solution obtained for a given problem should move towards the best solution leaving beside the worst solution.…”

A dynamic S-box generation based on a hybrid method of new chaotic system and DNA computing

“…In the last years, there have been some S-box design algorithms developed based on chaotic systems and DNA computation. Masood et al [13], presented an approach that integrates DNA sequencing code, Arnold transformation, and a chaotic dynamical system to produce an initial S-box. A number of experiments have been performed in order to verify the randomness of this newly generated S-box.…”
