基于超级混沌系统的图像加密算法
Image encryption algorithm based on chaotic theory
【摘要】 为了提高数字图像加密算法的安全性,提出一种基于超级混沌系统的图像加密算法。首先将原始明文图像进行分解,R,G,B三个分量,然后采用不同类型的混沌系统分别对R,G,B三个分量进行图像加密,最后把加密后R,G,B分量进行组合,得到最终密文图像,并采用仿真实验测试算法的性能。仿真结果表明,本文算法不仅增加了密钥的空间,而且提升提高抗攻击能力,可以获得十分理想的图像加密效果,很好的保护了图像中的信息安全。
【Abstract】 In order to improve the security of image encryption algorithm,a new image encryption algorithm based on chaotic theory is proposed in this paper.Firstly,the original image is decomposed into R,G,B components,and then R,G,B components of original image are encrypted by different chaotic systems,finally,the encrypted R,G,B components are combined to get the encrypt image,and simulation experiments are carried out to test the performance of encryption algorithm.The simulation results show that the proposed encryption algorithm can increase key space and enhance anti attack capability,and can acquire very good encryption effect and can protect the safety image very well.
