提出了一种新的基于超混沌和比特替换的图像加密算法.算法所采用的混沌系统为Hyperhenon映射和Kent映射
而且在加密过程中引入了与图像本身特性密切相关的参数.首先是利用Kent映射所产生的一组混沌序列来对明文图像位置进行置乱; 再通过Hyperhenon映射产生的混沌序列
结合该混沌序列的特性来对每个像素进行内部比特置乱和像素扩散
从而使明文图像达到更好地加密效果.实验仿真结果显示
新的加密算法既能较好地抵抗统计特性分析和差分攻击
又能有效抵抗选择明文(密文)攻击
还具有密钥空间大、加密效果好等优点.
We propose a new chaotic image encryption algorithm based on hyperchaotic and bit substitution.The algorithm uses Hyperhenon map and Kent map
and makes the encryption process be related closely with the plaintext images self characteristics. First
A chaotic sequence generated by Kent map is used to make image position global scrambling; Then
use Hyperhenon map to generate a chaotic sequence
and by using properties of the chaotic sequence to scramble internal bit of each pixel and pixel diffusion so that plain image information can be well hidden.The simulation results show that the algorithm can better resist statistical characterization
differential attack
and can effectively resist chosen plaintext (ciphertext) attacks
and have big key space
good encryption effect.
