“…And this system is better than the NIST test results of chaotic sequences generated by general high-dimensional chaotic systems. For example, the P value of each item is slightly higher than the P value of 15 tests in [ 41 ], which means it has better randomness. In addition, Wang et al [ 17 ] also tested the time series diagrams in each direction of x , y , z , w , and v , and they all showed a chaotic state, which also shows that the chaotic sequence generated by this system is more random.…”

Current image encryption methods have many shortcomings for the medical image encryption with high resolution, strong correlation and large storage space, and it is difficult to obtain reliable clinically applicable medical images. Therefore, this paper proposes a medical image encryption algorithm based on a new five-dimensional three-leaf chaotic system and genetic operation. And the dynamic analysis of the phase diagram and bifurcation diagram of the five-dimensional three-leaf chaotic system selected in this paper is carried out, and NIST is used to test the randomness of its chaotic sequence. This algorithm follows the diffusion-scrambling framework, especially using the principle of DNA recombination combined with the five-dimensional three-leaf chaotic system to generate a chaotic matrix that participates in the operation. The bit-level DNA mutation operation is introduced in the diffusion, and the scrambling and diffusion effects have been further improved. Algorithm security and randomness have been enhanced. This paper evaluates the efficiency of this algorithm for medical image encryption in terms of security analysis and time performance. Security analysis is carried out from key space, information entropy, histogram, similarity between decrypted image and original image, PSNR, correlation, sensitivity, noise attack, cropping attack and so on. Perform time efficiency analysis from the perspective of time performance. The comparison between this algorithm and the experimental results obtained by some of the latest medical image encryption algorithms shows that this algorithm is superior to the existing medical image encryption algorithms to a certain extent in terms of security and time efficiency.

“…The paper [12] proposed a color image encryption algorithm based on a double-chaos system and DNA computation at the bit level. This algorithm has used the Arnold algorithm to scramble the three color components of the plaintext image, and the number of iterations is determined by the pixel average of each component, which improved the scrambling effect of Arnold algorithm.…”

Currently, digital images are widely used in different applications to represent distinguishable contents. Also, diagnosing diseases using medical images became vital and crucial and if the data in these images are liable for unauthorized usage, this may lead to severe problems. The security of these data has become an urgent and serious problem and needs immediate attention. Traditional encryption and decryption algorithms are not sufficient to secure digital images. Especially, image encryption and decryption algorithms are needed. Securing image data with effective encryption approaches can be more useful for applications. This article aims to comparatively study the different digital image encryption algorithms. In the current Pandemic scenario of COVID-19, the variety of research work can be communicated through the encrypted images among researchers to avoid the leakage of information. These image encryption algorithms are having applications to secure image data and store and share them in the network environments.

“…In previous studies, some simple chaotic maps, such as one-dimensional maps and two-dimensional maps, have weak key spaces [41]- [46]. Their chaotic sequence orbits are simple [47], [48] and can be predicted by techniques such as regression mapping, phase space reconstruction, and nonlinear prediction. At the same time, the randomness of chaotic mapping will be significantly reduced in the digital domain, and it will be vulnerable to selected plaintext or known-plaintext attacks [49].…”

Compared with general chaotic systems, laser chaotic systems have more complex dynamic behaviors and extremely high sensitivity to parameters and initial values. So far, there are few studies on the application of laser chaotic systems to image encryption. Therefore, this paper proposes a new image encryption scheme based on an optical injection semiconductor laser chaotic system. The encryption scheme mainly includes two processes of scrambling and diffusion. The scrambling process converts the pseudorandom sequences generated by the laser chaotic system into chaotic matrixes and scrambling each pixel through a random point scrambling algorithm. In the diffusion process, the chaotic sequences generated by the laser chaotic system are quantized into random numbers and applied to the improved gravitational model algorithm to achieve the effect of pixel diffusion. The experimental results and security analysis indicate that the proposed algorithm has good image encryption performance and can effectively resist various common attacks on image encryption systems.
