Abstract

En 中文
This paper presents a novel one-dimensional Sine-Exponential chaotic system (SECS), which exhibits a broad parameter range and excellent chaotic properties, making it highly suitable for image encryption. Building on SECS, we propose a multi-image encryption algorithm. First, a dynamic stack scrambling algorithm is introduced to quickly scramble each plaintext image, effectively reducing pixel correlations within individual images. Next, DNA encoding is applied to all images, and a specially designed cross-plane scrambling algorithm is used to scramble different images, strengthening the pixel coupling across multiple images. Finally, DNA random operations, along with asymmetric DNA encoding and decoding rules, are utilized to achieve high-quality diffusion, generating multiple ciphertext images that match the size of the original plaintext images. This encryption algorithm is capable of securely encrypting images of varying quantities and sizes. Simulation results and comprehensive security analyses confirm the algorithm's robustness and high security.
