针对现有基于DNA序列的图像加密算法实验环境要求苛刻、难于实现的不足
根据DNA加密的基本思想
提出了一种伪DNA密码图像加密算法。该算法首先利用二维Logistic混沌序列对原始图像进行位置置乱
打乱像素之间的分布规律; 然后
将置乱图像转换为四进制序列
根据事先定义的编码规则采用动态DNA编码方法将四进制序列转换为DNA序列; 利用三维Chen混沌系统产生与四进制序列相同大小的DNA序列
将四进制编码的DNA序列和三维Chen混沌系统生成的DNA序列按照DNA异或规则进行异或运算; 最后
进行截取延长操作并进行DNA解码重组得到加密图像。实验结果表明
该算法不仅容易实现
而且加密速度快、安全性高
可用于军事、医疗、司法等涉及个人和单位隐私的数字图像的保密存储和网络传输。
Aiming at the fact that existing image encryption algorithms based on DNA sequence have strict experimental conditions and are difficult to implement
an image encryption algorithm based on pseudo DNA coding is proposed combining DNA coding and chaotic system. Firstly
the original image is scrambled by using two-dimensional chaotic system. Secondly
the scrambled matrix is transformed into quarternary sequence which is then converted to DNA sequence by using dynamic DNA coding method. Thirdly
generating a random DNA sequence by three-dimensional chaotic system
with the same size as the quarternary sequence. Then
implementing DNA XOR operation on the quarternary DNA sequence and the DNA sequence generated by three-dimensional chaotic system
the encrypted image is obtained by decoding and reorganization. The simulation results and analysis show that the algorithm has not only good encryption effect but also fast encryption speed and high safety
which can be applied to the storage and network transmission of military
medical
judicial and other digital images.
