A novel color image encryption method based on new three-dimensional chaotic mapping and DNA coding

In recent years, the field of information science has seen a surge in research focused on digital image security. Chaotic systems have emerged as essential tools in the development of image encryption algorithms due to their unpredictability and sensitivity to initial values. In this paper, a novel three-dimensional chaotic system is proposed and its chaotic behavior is validated through an analysis of dissipative properties, phase diagrams, spectral entropy, Lyapunov indices, etc., and more. Leveraging chaotic mapping, a color image encryption algorithm utilizing rotational arithmetic element shuffling and DNA coding is proposed and executed. Validation through simulation experiments and numerical analyses demonstrates the algorithm’s reliability and security.
