适合 51单片机的AES加密,对算法进行了优化，节省了内存开销，使用特殊的加法和乘法，是基于近代数学的域论的有限域GF(28).   *           GF(28)由一组从 0x00 到 0xff 的256个值组成，加上加法和乘法。 GF代表   *           伽罗瓦域，以发明这一理论的数学家的名字命名。GF(28) 的一个特性是一个   *           加法或乘法的操作的结果必须是在{0x00 ... 0xff}这组数中。虽然域论是相   *           当深奥的，但GF(28)加法的最终结果却很简单。GF(28) 加法就是异或（XOR）   *           操作。 

另外的一个词法分析器，包含了一个文件，还有一个实验报告。(In addition, a lexical analyzer, contains a file, and a test report.)
