通过上机操作，使学生对高级加密标准AES算法的执行过程、密钥编排方案和加密算法的实现过程等有一个更加清晰地认识。通过本次实验，加深学生对分组密码的认识。(Through the operation of the computer, we have a clearer understanding of the implementation process of the AES algorithm, the key arrangement scheme and the implementation process of the encryption algorithm. Through this experiment, the students' understanding of the block cipher is deepened)
