我们这里只谈序列密码几种见到的算法。不涉及其他方面的的加密算法。一、延长部份众就周知,现在用序列加密的密码机密钥一般总在10~(20)～10~(80)范围之内,而它都小于300位二进制,所以用它来直接加密,即使在最常用的32千赫调制的语音下,一秒钟也得重复一百多次,因此是不可取的,而都是以这个密钥为基础产生周期极长的,有时
Here we only talk about the sequence of passwords to see a few of the algorithms. Does not involve other aspects of the encryption algorithm. First, to extend the part of the public are well known, and now use sequence encryption password machine keys are generally always in the range of 10 ~ (20) ~ 10 ~ (80), and it is less than 300 binary, so use it to directly encrypt , Even in the most commonly used 32 kHz modulation voice, one second has to repeat more than one hundred times, it is not desirable, but are based on the key to produce a very long period, and sometimes
