说明：  AES加密解密算法,AES 算法是基于置换和代替的。置换是数据的重新排列，而代替是用一个单元数据替换另一个。AES 使用了几种不同的技术来实现置换和替换。为了阐明这些技术，让我们用 Figure 1 所示的数据讨论一个具体的 AES 加密例子。
(AES encryption and decryption algorithm, AES algorithm is based on the replacement and substitute. Replacement is to rearrange data, and to replace a unit of data used to replace another. AES using several different techniques to achieve the replacement and replacement. In order to clarify these technologies, so we use the data shown in Figure 1 to discuss a specific example of AES encryption.)
