| 摘 要： | 提出一个基于位平面彩色图像Arnold映射置乱和采用Chen系统产生的混沌序列加密算法。首先采用由Logistic系统构造的非线性动力系统产生的混沌序列形成Arnold映射矩阵,在不同的位平面对彩色图像进行置乱,然后用Chen系统产生的混沌序列对置乱后的图像进行加密。该算法实现简单,能够抵御各种攻击,且容易用硬件实现。

| Abstract: | Presented an image encryption algorithm based on bit plane color image Arnold disorder approach and the chaotic sequence that is produced by Chen's system.First,the mapped matrixes of Arnold,which their elements are made up of the chaotic sequences that are produced by the Logistic dynamic system, are used for disordering the color image in different bit planes to produce disordered image.Then,the image is encrypted by means of the chaotic sequence that is produced by the Chen's system.The algorithm is very simple,can resist various attacks,and is implemented by means of hardware. |
