摘要：
This article describes the application of chaotic Josephus scrambling and RNA computing in image encryption. The algorithm uses the classical 'scrambling-diffusion' process, and the pseudo-random sequences used in each stage are generated by the hyper-chaotic Lorenz system. Firstly, during the scrambling phase, the randomness of the traditional Josephus traversal sequence is improved by using chaotic mapping, which makes the image scrambling effect better. Then during the diffusion phase, the gray value of the pixel is modified by using RNA modular operation and random substitution of RNA codons. The research results prove the feasibility of the encryption system.
