摘要:提出了一种基于Lorenz混沌系统的自适应图像加密算法.首先利用Lorenz混沌系统对原始图像进行自适应置乱加密,然后利用改进的Lorenz系统混沌序列对图像进行替换加密.实验表明该算法安全性较高,具有较强的抵御穷举攻击、统计攻击能力.

Abstract: An adaptive image encryption algorithm based on Lorenz system is put forward.Firstly,scrambling algorithm of the original image was achieved by adaptive algorithm,then the image was substitution encrypted based on the Lorenz chaotic system.The experiment results showed that the algorithm has stronger resistance to exhaustive and statistical attacks,and it is of high security.
Key words: Lorenz system, image encryption, substitution, scrambling
