11DES_encryption

文件里是一个非常新颖的matlab程序，对研究碰撞和摩擦理论的人来说是非常值得参考的程序。(File is a very novel matlab program, the study of the collision and friction theory for people who are very good reference procedures,)

一个简单的m序列产生函数，通过调用primpoly获得本原多项式，然后通过移位循环寄存器产生所需要的序列。自相关图形上能看到峰值旁瓣电平(PSL)和积累旁瓣电平(ISL)。(A simple code for generate m-series pseudo-random sequence based PRIMPOLY function which we get the prime polynomials first,then we get the feedback connect coefficient of the cycle shift registers which generate m-series sequency. the PSL and ISL of autocorrelate function is computed on the figure. )
