Summary: This paper proposes a new medical image encryption scheme based on a new hyperchaotic map. The scheme demonstrates excellent security and efficiency, suitable for medical images with distinctive formats. A two-dimensional Logistic-Gaussian hyperchaotic map (2D-LGHM) is constructed, which exhibits superior ergodicity and unpredictability. The scheme utilizes chaotic sequences to break correlation between pixels and modify global pixel values. Tests on diverse medical images show that the scheme is highly robust and effective against security attacks and data loss.

Summary: In order to address the issues of existing chaotic systems including simple permutation-diffusion structure, low encryption efficiency, and limited chaos range, this paper proposes a hyperchaotic image encryption algorithm based on LSTM neural network and lifting wavelet transform. A new hyperchaotic system is constructed by building upon the Lorenz chaotic system, which possesses more complex dynamic characteristics and higher Lyapunov exponent. The proposed algorithm utilizes lifting wavelet transform and zigzag conversion algorithm for image encryption, and integrates a trained LSTM neural network to generate a second key for encryption using Henon chaotic sequence, effectively preventing chosen-plaintext attack. Experimental results demonstrate that the proposed algorithm exhibits good performance in key security, differential attack, statistical analysis, and operation efficiency, indicating its high security level.

Summary: Chaotic maps are commonly used in image encryption, but many of them have limited chaotic ranges. To address this issue, a new chaotic map is proposed by combining modular sinusoidal discrete memristor and classical sine map. An image encryption algorithm is developed based on this new chaotic map, which allows controlling the encryption time by adjusting the block size. The algorithm consists of random-cross permutation and alternate-plane diffusion, which shuffle the pixels and process the image using chaotic sequences, respectively. Simulation experiments and performance analysis demonstrate the effectiveness and reliability of the proposed encryption algorithm.

Summary: Discrete chaotic synchronization is crucial in secure communication, but some systems cannot achieve the required synchronization. In this study, a new algorithm blended with error control was proposed to design an inverse discrete chaotic synchronization system. By controlling the coefficient matrix of the system based on the eigenvalues of the synchronization error system, the positive Lyapunov exponents in the system can be precisely controlled. The results showed that the error control-blended inverse discrete chaotic synchronization system had good chaotic characteristics and high reliability and flexibility.
