研究了最近发展起来的一种基于进化的图像加密算法。提出了一种基于脱氧核糖核酸(DNA)掩蔽、遗传算法(GA)和Logistic映射混合模型的图像加密算法。该研究使用DNA和Logistic映射函数来创建初始DNA掩码的数量，并应用遗传算法来确定最佳加密掩码。这种方法的显著优点是提高了DNA掩模的质量，以获得与普通图像兼容的最佳掩模。实验结果和计算机模拟都证实了该方案不仅具有良好的加密性能，而且能够抵抗各种典型的攻击。(C)2013爱思唯尔有限公司。保留所有权利。
The paper studies a recently developed evolutionary-based image encryption algorithm. A novel image encryption algorithm based on a hybrid model of deoxyribonucleic acid (DNA) masking, a genetic algorithm (GA) and a logistic map is proposed. This study uses DNA and logistic map functions to create the number of initial DNA masks and applies GA to determine the best mask for encryption. The significant advantage of this approach is improving the quality of DNA masks to obtain the best mask that is compatible with plain images. The experimental results and computer simulations both confirm that the proposed scheme not only demonstrates excellent encryption but also resists various typical attacks. (C) 2013 Elsevier Ltd.
