“…There are some papers focusing on designing S-box with chaotic maps [9,10,11,12]. In [6,13,14,15,16,17,18,19,20], the analyzed image encryption schemes are fixed to withstand the proposed attacking methods. Due to the seemingly similar properties of a chaotic system and a secure pseudo-random number generator (PRNG), a large number of image encryption schemes use various chaotic maps to generate PRNS, which is used to control combination of some basic encryption operations, e.g.…”

This paper aims to review the encountered technical contradictions when an attacker meets the cipher-images encrypted by the image encryption schemes (algorithms) proposed in 2018 from the viewpoint of an image cryptanalyst. The most representative works among them are selected and classified according to their essential structures. Almost all image cryptanalysis works published in 2018 are surveyed due to their small number. The challenging problems on design and analysis of image encryption schemes are summarized to receive the attentions of both designers and attackers (cryptanalysts) of image encryption schemes, which may promote solving scenario-oriented image security problems with new technologies.

“…While new chaotic image encryption algorithms are constantly proposed, cryptographic analysis of the chaotic image encryption algorithms is also continually carried out. Many image encryption algorithms based on chaos have been cracked due to their inability to resist selected-plaintext attacks and known-plaintext attacks [25]- [27]. Scholars analyzed the disadvantages of low-dimensional chaotic encryption technology, such as low sensitivity to keys, the existence of periodic windows, the lack of defense against chosen-plaintext attack [28], [29], and the computational complexity of attacks being lower than that of brute attacks [30].…”

To improve the abilities of image encryption systems to resist plaintext attacks and differential attacks, a novel plaintext-related image encryption scheme based on Josephus traversing and pixel permutation is proposed. In this scheme, the step sizes of the Josephus traversing are associated with the pixel values, and the Josephus traversing method is improved, increasing the dependence of the cipher image on the plaintext image, further enhancing the plaintext sensitivity of the algorithm, and reducing the number of iterations of the index sequence generated by the chaotic system. By segmenting the image and combining a chaotic system, bit XOR and crossover operations between the modules are performed to achieve the effects of confusion and diffusion, and the randomness of the cipher image is improved. Finally, the confusing and spreading characteristics of the algorithm are further enhanced by cipher feedback. The experimental results and security analysis show that the proposed algorithm is sensitive to keys and can effectively resist attacks such as statistical attacks, selective-plaintext attacks and exhaustive attacks. The algorithm has high potential for real-time and secure image applications.

“…In recent years, many chaotic image encryption algorithms have been cracked [5], [15], [16], [33]- [47]. For examples, Li et al [36] cryptanalyze a chaotic image encryption algorithm whose chaotic sequences are generated by a simple nonlinear first-order time-delay system, and point out three defects of this algorithm; Hu et al [37] cryptanalyze a chaotic image cipher using the latin-square-based confusion and diffusion. And they demonstrate that the cipher can be broken by chosen-plaintext attack combined with chosen-ciphertext attack; Wen et al [38] investigate the security of a hyper-chaotic image encryption algorithm with an architecture of permutation and diffusion.…”

A Plain-Image-Related Chaotic Image Encryption Algorithm Based on DNA Sequence Operation and Discrete Logarithm

According to the research works of the literatures on chaotic cryptanalysis, many recent chaotic image encryption algorithms cannot resist chosen-plaintext attack. Although some chaotic image encryption algorithms introduce plain-image information, they still violate some design requirements of modern cryptosystems. Therefore, after analyzing many literatures related to chaotic image encryption, we propose a plain-image-related chaotic image encryption algorithm based on the deoxyribonucleic acid (DNA) sequence operation and discrete logarithm. As we know, the discrete logarithm calculation is a complex non-linear calculation, introducing it can increase the complexity of the encryption process. More importantly, discrete logarithm values are significantly different under different generators, and the multiplicative group adopted in the proposed algorithm has as many as 128 generators. Therefore, by using two generators determined by the secret key and the hash value of the plain-image respectively, we not only expand the key space, but also greatly improve the plain-image sensitivity and plain-image relevancy of the encryption process. In addition, the proposed algorithm improves the way of using the hash value of the plain-image. In this way, once the secret key is selected, chaotic sequences can be generated in advance and reused to improve the encryption efficiency. Similarly, the proposed algorithm also introduces the DNA sequence operation with high parallelism to further improves the encryption efficiency. Simulation tests and comparative analyses show that the proposed algorithm can not only resist common attacks, but also outperform some recent chaotic image encryption algorithms in many aspects.
