“…Currently, most image encryption algorithms are based on pixel-level scrambling-diffusion [ 15 , 16 , 17 , 18 , 19 ]. Because bit-level operation can achieve better scrambling and diffusion effect, the bit-level operation is often used in some encryption schemes [ 20 , 21 , 22 ]. For example, Sujarani et al [ 20 ] proposed a dynamic bit-flip diffusion image encryption algorithm.…”

“…Zhu et al [ 21 ] proposed a 3D bit-level image encryption scheme using Rubik’s cube method. Li et al [ 22 ] proposed an image encryption scheme combining bit-level scrambling and multiplication diffusion. However, algorithms based on bit-level operations need to process eight times as much data as those based on pixel-based operations.…”

To address the problem of a poor security image encryption algorithm based on a single chaotic map, this paper proposes a cascade modulation chaotic system (CMCS) that can generate multiple chaotic maps. On this basis, a multi-image encryption algorithm with block-scrambling-diffusion is proposed using CMCS. The algorithm makes full use of the features of CMCS to achieve the effect of one encryption at a time for images. Firstly, the key-value associated with the plaintexts is generated using a secure hash algorithm-512 (SHA-512) operation and random sequence, and the three images are fully confused by the double scrambling mechanism. Secondly, the scrambled image is converted into a bit-level matrix, and the pixel values are evenly distributed using the bit-group diffusion. Finally, the non-sequence diffusion of hexadecimal addition and subtraction rules is used to improve the security of the encryption algorithm. Experimental results demonstrate that the encryption algorithm proposed in this paper has a good encryption effect and can resist various attacks.

“…Chaos is a physical phenomenon highly sensitive to initial value. Its development and the related research have made great progress in just a few decades, meanwhile, the study of the chaotic system [1][2][3][4][5][6][7][8][9][10][11] has gradually expanded to weather, finance, communication and other fields. Due to the study of the chaotic system model, many different types of chaotic systems have been derived, such as the discrete chaotic system [12][13][14], the memristor chaotic system, the hyperchaotic system [15][16][17][18] and so on.…”

In this paper, a new six dimensional memristor chaotic system is designed by combining the chaotic system with a memristor. By analyzing the phase diagram of the chaotic attractors, eleven different attractors are found, including a multi-wing attractor and symmetric attractors. By analyzing the equilibrium point of the system, it is proven that the system has the property of a hidden chaotic attractor. The dynamic behavior of the system when the three parameters change is analyzed by means of LEs and a Bifurcation diagram. Other phenomenon, such as chaos degradation, coexistence of multiple attractors and bias boosting, are also found. Finally, the simulation on the DSP platform also verifies the accuracy of the chaotic system simulation. The theoretical analysis and simulation results show that the system has rich dynamical characteristics; therefore, it is suitable for secure communication and image encryption and other fields.

“…This algorithm uses the method of different directions of odd and even lines to traverse and scramble the image and proposes a new scrambling method based on the idea of sawtooth scrambling to improve the encryption effect of the image. ChunLai Li et al [ 5 ] proposed a grayscale image encryption technology scheme based on bit-level scrambling and multiplicative diffusion architecture. Firstly, binary tree scrambling, flip scrambling, and improved circular index scrambling are used to achieve scrambling, and then the improved GF (257) field multiplication is used to diffuse the scrambled components to improve the security of image encryption.…”

Information security has become a focal topic in the information and digital age. How to realize secure transmission and the secure storage of image data is a major research focus of information security. Aiming at this hot topic, in order to improve the security of image data transmission, this paper proposes an image encryption algorithm based on improved Arnold transform and a chaotic pulse-coupled neural network. Firstly, the oscillatory reset voltage is introduced into the uncoupled impulse neural network, which makes the uncoupled impulse neural network exhibit chaotic characteristics. The chaotic sequence is generated by multiple iterations of the chaotic pulse-coupled neural network, and then the image is pre-encrypted by XOR operation with the generated chaotic sequence. Secondly, using the improved Arnold transform, the pre-encrypted image is scrambled to further improve the scrambling degree and encryption effect of the pre-encrypted image so as to obtain the final ciphertext image. Finally, the security analysis and experimental simulation of the encrypted image are carried out. The results of quantitative evaluation show that the proposed algorithm has a better encryption effect than the partial encryption algorithm. The algorithm is highly sensitive to keys and plaintexts, has a large key space, and can effectively resist differential attacks and attacks such as noise and clipping.
