基于henon映射的加密程序。首先生成混沌序列，利用henon映射生成两个长度为（M*N）/2的序列。其次，将混沌序列置乱。最后，异或运算:将初始图像进行排序变换，做异或运算，从而实现对初始图像的置乱加密，得到最终的加密图像。-Based henon mapping encryption programs. First generate chaotic sequence, using henon mapping generates two length (M* N) sequence/2. Secondly, the chaotic sequence scrambling. Finally, XOR: sort transform the initial image, do XOR, enabling the initial image scrambling encryption, to get the final encrypted image.
