中文摘要: 针对低维混沌系统和单一的DNA加密方案的空间小、复杂度低等问题,提出一种基于多混沌映射与DNA的彩色图像加密算法.先利用Arnold变换对图像每分量进行图像位置置乱,利用Logistic混沌映射产生与明文图像大小相同的随机矩阵并进行分块操作,再进行DNA规则运算,其运算方式由Chen超混沌系统产生的混沌序列动态决定.仿真实验结果表明,算法加密与恢复效果良好,能有效地抵御各种统计攻击与差分攻击,具有良好的安全性、抗噪声性好、复杂高等加密性能.

Abstract:Aiming at the problems of small space and low complexity of low-dimensional chaotic system and single DNA encryption scheme, a color image encryption algorithm based on multi-chaotic mapping and DNA is proposed. Firstly, Arnold transform is used to scramble the position of each component of the image. Logistic-sine chaotic map is used to generate random matrices of the same size as the plaintext image and block them. Then DNA rule operation is performed. The operation mode is determined dynamically by the chaotic sequence generated by Chen hyperchaotic system. The simulation results show that the algorithm has good encryption and recovery effect, can effectively resist various statistical attacks and differential attacks, and has good security, anti-noise, complex and high encryption performance.
