- 压缩包内论文只是通过对一个简单的密码体制：仿射密码（Affine Cipher）的分析、设计和实现来说明简单的加密思想，从这个思想我们可以研究更复杂的加密算法。最后，我以软件的形式将其实现，通过测试，发现使用效率还可以；但是，这只是个实验性的设计，要想不被人破译，还需要更复杂的密钥空间和更难的算法。-compressed within the papers only through a simple password system : Affine password (Affine Cipher

Vigenere
- 为了提高密码的破译的难度，人们有发明一种多表置换的密码，即一个明文字母可以表示为多个密文字母，多表密码加密算法结果将使得对单表置换用的简单频率分析方法失效，其中维吉尼亚密码就是一种典型的加密方法。维吉尼亚密码是使用一个词组（语句）作为密钥，词组中每一个字母都作为移位替换密码密钥确定一个替换表，维吉尼亚密码循环的使用每一个替换表完成明文字母到密文字母的变换，最后所得到的密文字母序列即为加密得到的密文(In order to improve the difficulty of deciphering
