1、 实验要求：用高级语言编写求自由距离的程序-1, the experimental requirements: high-level language used for the preparation of the procedures from the Freedom

AES相关的一些列子,需要库的支持才能应用-AES related some Liezi need the support of the Treasury to apply

这本书包括了密码学和水印学竞争在内的各方面技术，这本书的内容覆盖知识范围广博，书中还有经过整理的代码，源代码等。-This book includes the study of cryptography and watermarking competition, including all aspects of technology, the content of this book cover a broad range of knowledge, the book also after finishing the code, source code and so on.

Fountain Encoding Algrothm

128位(或192或256bit该代码以128为例)的密钥长度和分组长度，数据分组（输入的明文），先进行逐比特异或（AddRoundKey） 运算。然后通过循环十次非线性代换（SubBytes）、行变换（ShiftRows）、列变换（MixColumns）、逐比特异或【最后一轮不进行列变换】 的过程，输出128位（或192或256bit）数据即是密文。这就是加密过程。之后进行之前的逆过程，即可得到明文，此为解密过程。
