我们提出一种利用随机二进制编码和旋转变换的双图像加密方法。首先将两幅秘密图像视为复函数的实部和虚部。利用混沌映射获取随机二进制矩阵。在随机二进制数据的控制下交换复函数的实部和虚部。设计并采用一种由随机二进制编码方法组成的迭代结构，以增强加密算法的安全性。混沌映射和旋转变换中的参数作为该加密方案的密钥。进行了一些数值模拟，以证明该算法的性能。（C）2010美国光学学会
We propose a double image encryption by using random binary encoding and gyrator transform. Two secret images are first regarded as the real part and imaginary part of complex function. Chaotic map is used for obtaining random binary matrix. The real part and imaginary part of complex function are exchanged under the control of random binary data. An iterative structure composed of the random binary encoding method is designed and employed for enhancing the security of encryption algorithm. The parameters in chaotic map and gyrator transform serve as the keys of this encryption scheme. Some numerical simulations have been made, to demonstrate the performance this algorithm.
