单字母表：
明文 a b c d e f g h i j k l m n o p q r s t u v w x y z
密文 z s e x d r c f t g y b h u n i m k o l p q a

根据单字母表，译出明文：
the time has come the walrus said to talk of many things
of shoes and ships and sealing wax of cabbages and kings
of why the sea is boiling hot and whether pigs have wings
but wait a bit the oysters cried before we have out chat
for some of us are out of breath and all of us are fat
no hurry said the carpenter they thanked him much for that

楼上的，详细说说方法呀

[inanition]

楼上的楼上的，是根据字母出现的频率对号入座破解的吗？讲讲方法嘛。

[AaronTJ]

对不起，很久没来了
其实这个也就是单字母替换
根据字母出现频率和单词组成构建替换表
可参考Andrew S. Tanenbaum的Computer Networks Fourth Edition
第八章Network Security中有关内容
