1）利用CC++语言实现给定的LFSR； 2）通过不同初始状态生成相应的序列，并观察它们的周期有什么特点； 3）利用生成的序列对文本进行加/解密（按对应位作模2加运算）。 给定的LFSR为：(1) the use of C C++ language given LFSR 2) to generate the corresponding sequences by different initial state, and observe what are the characteristics of their cycle 3) using the generated sequence of text encryption/decryption (press the corresponding bit for modulo-2 addition operation). LFSR given as follows:)
