“…where Q(γ , β) represents the quantum chaotic system, F(Q(γ , β)) is the chaotic sequence generated by (8), and L(x 0 , µ) represents the Logistic chaotic system with an initial value x 0 and a parameter r. Finally, a new uncorrelated chaotic sequence is generated by coupling with the Logistic map.…”

“…A chaotic sequence is created by a chaotic map as a random sequence. Chaotic sequences are complex in structure and cannot be analyzed and predicted [7], [8], so they are widely used in image encryption. Many chaos-based encryption algorithms have been extensively studied and applied to the two steps of the common chaotic encryption scheme-scrambling and diffusion.…”

This paper proposes a color image encryption algorithm based on a cloud model Fibonacci chaotic system, as well as a matrix convolution operation that can protect image content effectively and safely. The algorithm combines the cloud model with the generalized Fibonacci, creating a new complex chaotic system that realizes the dynamic random variation of chaotic sequences. The chaotic sequence is used to scramble the pixel coordinates of the mosaic images of the R, G, and B components of the color image. Then, the chaotic sequence value is used as a matrix convolution cloud algorithm that alternately updates the input value of the matrix convolution operation and the pixel value to obtain the permutation transformation of the original pixel value. Finally, the pixel values of the replacement and cloud model Fibonacci chaotic sequence and the pixel values of the front (rear) adjacent pixel points are subjected to a two-way exclusive XOR operation. Realizing the change of the arbitrary pixel value causes a chain transformation of the pixel values of all of the pixel points, and sequentially generates an encrypted image. Experiments show that the histogram of the encrypted image is smoother and adjacent pixels of the image have low correlation. In addition, this algorithm can resist attack experiments such as differential attack, select plaintext attack and noise attack and provides high encryption security, high anti-interference, and strong robustness. The dynamic chaotic system is used to realize the color image encryption of the dynamic key, and the encryption algorithm has higher security and the validity of the algorithm.

The paper describes a symmetric encryption algorithm based on bit permutations and using an iterative process combined with a chaotic function. The main advantages of such a cryptosystem is its ability to encrypt securely bit sequences and assuring confusion, diffusion and indistinguishability properties in the cipher. The algorithm is applied on the image encryption where the plain-image is viewed as binary sequence. The results of statistical analysis about randomness, sensitivity and correlation on the cipher-images show the relevance of the proposed cryptosystem.

“…The main concern of such algorithms is to meet the demand for fast and highly secure image transmission. There are two major groups of digital image encryption algorithms: non-chaos selective methods (i.e., traditional algorithms) and Chaos-based selective or non-selective methods [5]. Unfortunately, traditional image encryption algorithms were reported with low-level efficiency [2].…”

This paper proposes a robust image encryption algorithm via Smooth Exponential Map (SEM) to meet the demand for fast and highly secure image transmission. The proposed algorithm consists of two phases; image-diffusion and image-fusion. In the image diffusion phase, pixel locations of the original image are shuffled in the spatial domain while pixel values are modified in the image fusion phase. Investigating the chaotic map characteristics of proposed SEM indicates a full chaotic behavior. Results of testing the proposed algorithm show that the proposed algorithm has a large key space with complete obscuring of the original image, secured against brute-force attack as it is achieved a large complexity of order   90 2 O , and requires 343ms to encrypt 200x200 pixels image.
