High Intensity Image Encryption Scheme Based on Quantum Logistic Chaotic Map and Complex Hyperchaotic System

In this paper, a novel encryption algorithm based on quantum chaotic map and four-wing complex system is proposed. Dynamical performances of the two system are revealed by phase portraits, Lyapunov exponent spectrum, bifurcation diagram analyses and complexity entropy. Based on these analyses, an encryption algorithm is designed by the two chaotic system and DNA coding. Firstly, in process of permutation operation, quantum logistic map is utilized to generate chaotic sequences for disrupting the position of each pixel point combine with Arnold transformation. Then, using the complex hyperchaotic system, the value of each pixel is diffused through mathematical operation and DNA encoding. Finally, security performance is analyzed. Simulation results demonstrate that the algorithm has good robustness and high-quality performance, and it can effectively protect the subject image and resist conventional attack. This encryption scheme can provide a new realization method for security transmission and protection of image information.
