摘要

在数字时代，加密算法在网络安全领域的重要性显著增加。本研究提出了一种创新的图像加密方法，消除了传统一维逻辑映射的安全限制。这种方法依赖于增强型二维逻辑-分数混合混沌映射（2D-LFHCM）和脱氧核糖核酸（DNA）计算。首先，利用改进的二维逻辑分数混合混沌映射（2D-LFHCM），结合混沌序列对图像进行有效扰乱。然后，引入两种新的代数 DNA 计算规则来增强扩散加密。实验结果表明，即使面对著名的攻击，这种方法也能提供卓越的安全性能。

A novel image encryption method based on improved two-dimensional logistic mapping and DNA computing

In the digital era, the significance of cryptographic algorithms has grown significantly within the realm of cybersecurity. This research presents an innovative approach to image encryption that eliminates the security limitations of the conventional one-dimensional logistic mapping. This approach relies on an enhanced two-dimensional logistic-fraction hybrid chaotic mapping (2D-LFHCM) and deoxyribonucleic acid (DNA) computing. Initially, the improved 2D-LFHCM is utilized to effectively scramble the image by incorporating chaotic sequences. Then, two novel algebraic DNA computing rules are introduced to enhance diffusion encryption. Experimental findings show that this approach offers superior security performance, even with renowned attacks.
