摘要
提出了将Logistic映射、Henon映射和Rijndael加密算法相结合的数字图像加密算法.该方法先经Logistic混沌和Henon进行像素乱序和灰度置乱,然后用Rijndael加密算法进行像素加密形成密文图像.理论分析和仿真实验表明该算法加密效果良好、密钥空间足够大,加密后的图像抗攻击性得到进一步地提高,有很强的实用性.
An image encryption algorithm,based on Logistic map,Henon map and Rijndael algorithm,was presented.The scrambling transformation and gray transformation were completed with Logistic chaos and Henon chaos.Then Rijndael algorithm was used to deal with the last encryption.The results show that the proposed image encryption algorithm provides perfect results,larger key space,and the anti-attack performance of encrypted image is further improved,so this encryption algorithm has strong practicality.
