提出了一种新的基于DNA序列加法运算和混沌的图像加密方案。首先对原始图像进行编码得到DNA序列矩阵，然后将DNA序列矩阵分成若干个相等的块，利用DNA序列加法运算将这些块相加。接下来，通过使用两个Logistic映射对相加矩阵的结果执行DNA序列互补操作。最后对第三步得到的DNA序列矩阵进行解码，得到加密图像。仿真实验结果和安全性分析表明，该方案不仅能实现较好的加密效果，而且能抵抗穷举攻击、统计攻击和差分攻击。(C)2010爱思唯尔有限公司版权所有。
A new image encryption scheme based on DNA sequence addition operation and chaos is presented. First, a DNA sequence matrix is obtained by encoding the original image, then, divide the DNA sequence matrix into some equal blocks and use the DNA sequence addition operation to add these blocks. Next, perform the DNA sequence complement operation to the result of the added matrix by using two Logistic maps. Finally, decode the DNA sequence matrix from the third step, and we can get the encrypted image. The simulation experimental results and security analysis show that our scheme not only can achieve good encryption, but can also resist exhaustive attack, statistical attack and differential attack.
