线性反馈移位寄存器(Linear Feedback Shift Register,LFSR)是一种常用的伪随机数生成器,其基本原理是通过特定的反馈策略,将一个n位的二进制数向左或向右循环移位,产生新的随机数。 下面是一个使用Python实现的伽罗瓦LFSR算法的例子: ```python def galois_lfsr(state, taps): """ Galois LFSR algorithm. Paramete...
The most common algorithm is the sliding window algorithm. This algorithm uses a sliding window of a fixed size to compare the bits of the data stream with the expectedpattern of the LFSR. When the sliding window matches the expected pattern, the data stream is considered to be aligned. ...

实际上的序列密码基本原理如图所示: 从图中可以出密钥流的产生与明文消息流相互独立,即密钥序列产生算法与明文无关。所产生的密钥序列也与明文无关。因此在通信过程中,通信的双方必须保持同步,接收方才可以正确机密。如果传输过程中丢失或增加了一比特信息,则该比特后的数据将全部解密失败。 一种得到长伪随机数的方法...
