基于m序列的图像置乱技术

Image Scrambling Technology Based on m Sequence

简要论述了m序列的基本原理,利用m序列发生器中移位寄存器状态的遍历性(全零状态除外),提出了一种基于m序列的图像置乱方法,在MATLAB 7.0环境下编程实验,通过一个实例证明了此方法的可行性。

This paper introduces the principal of m sequence in shortly. Based on the ergodicity of the shifters （ except for all zero-states） in m sequence generator, we put forward a method for scrambling image and then carry out the experiment by programming in MATLAB 7.0 to prove its feasibility.
