提出了一种基于混沌映射和Hartley变换的彩色图像加密算法。利用Baker映射对彩色图像的三个分量进行置乱。将由加扰单色分量组成的坐标从笛卡尔坐标转换为球坐标。对方位角数据进行归一化处理,并将其作为关键。利用光学哈特莱变换对卫星的半径和天顶角数据进行加密。设计了一种光电加密结构。最后的加密图像是由两个选定的颜色分量的输出在真实的数域。
We present a color image encryption algorithm by using chaotic mapping and Hartley transform. The three components of color image are scrambled by Baker mapping. The coordinates composed of the scrambled monochrome components are converted from Cartesian coordinates to spherical coordinates. The data of azimuth angle is normalized and regarded as the key. The data of radii and zenith angle are encoded under the help of optical Hartley transform with scrambled key. An electro-optical encryption structure is designed. The final encrypted image is constituted by two selected color components of output in real number domain.
