“…Chaotic systems are often employed in the field of image encryption because of its own characteristics [4,5]. To improve the chaotic performances of Logistic, Sine and Tent maps, Mansouri et al designed a one-dimensional (1D) chaotic map amplifier, which can significantly increase the chaotic range [6].…”

The security of digital images has become increasingly important as information technology has advanced considerably. To ensure image security and improve the efficiency of image encryption, a novel color image encryption algorithm is proposed in this paper. Firstly, a novel three-dimensional chaotic system with extreme multistability is proposed and employed to generate the chaotic sequences to be used in the permutation and diffusion processes. Secondly, the proposed bidirectional spiral transformation is used to permute the R, G and B components extracted from the color plain image. Thirdly, the permuted pixel sequence is dynamically encoded into a DNA sequence. To further increase the permutation effect, the DNA sequence is permuted again using the index sequence. Finally, the dynamical DNA operations are performed to diffuse the permuted DNA sequence, and the designed look-up table method is used to quickly obtain the DNA operation results. The key space of the proposed algorithm is 10266, which is large enough to resist the brute-force attacks. The average entropy value of the cipher image of Peppers is 7.9971, which is much closer to the theoretical entropy value 8. The dynamic DNA operations process only takes up 0.032349s, which shows the advantage of the proposed look-up table method. Therefore, the proposed algorithm can be applied to the application that require high confidentiality and real-time.

Encryption is one of the measures that ensure the security of images used in various fields such as military understanding, secure clinical imaging offices, Internet and intranet media, electronic banking, and individual association images such as Facebook, WhatsApp, Twitter, etc. On this huge number of images that are sent in a free and open link either during selection or messaging; Then their security ends up being a central need in individual insurance organizations and the arrangement. This article audits and summarizes various image encryption systems to further develop advanced image encryption strategies that operate with expanded flexibility and security.

“…Chaotic systems are nonlinear dynamical systems exhibiting chaotic behavior and are highly sensitive to initial states [23]. Chaotic systems can be classified into low-dimensional systems (e.g., logistic maps or Henon maps) and highdimensional systems (e.g., Lorenz systems or Chua systems) [19]. High-dimensional chaotic systems possess more complex dynamics and attain much larger key spaces.…”

This research work extends the hyperchaotic 4D Chen system into the fractional-order domain to carry out image encryption over 3 stages. For the first encryption stage, the discrete Fourier transform (DFT) of the numerical solution of the fractional-order Chen system is obtained, quantized, and employed in carrying out DNA coding. For the second stage, a robust S-box is constructed from the DFTquantized solution of the Chen system and applied. For the third stage, a Mersenne Twister encryption key is converted to base-ϕ, and a modulo operation is applied. The proposed technique is shown to be efficient, secure, and robust, performing comparably to its counterparts in the literature. Average computed values include an MSE of 9610, a PSNR of 8.33 dB, an MAE of 80.22, an information entropy of 7.999, correlation coefficients of zero, an NPCR of 99.62%, and a UACI of 31.46%. It also passes all the NIST SP 800 suite of tests. The main advantages of the proposed technique are its superior key space of 2 1754 and encryption rate of 72.6 Mbps.
