摘　　要：随着飞行参数记录器中的数据敏感性越来越高,进行加密处理的需求越来越强烈.文中提出一种基于AES加密理论的实现方法,明文经过分块、字节代换、行移位、列混合以及轮密钥加等运算后得到相应的密文.经电脑端与微处理器端进行数据测试,结果表明加密算法可以正常运行,加密效果符合预期,具备工程化的可行性.With the increasing sensitivity of data in flight parameter recorder,the demand for encryption processing is becoming stronger and stronger.This paper presents an implementation method based on AES encryption theory.The plaintext obtains the corresponding ciphertext after block,byte substitution,row shift,column mixing and round key addition.Through the data test of computer and microprocessor,the results show that the encryption algorithm can run normally,the encryption effect is in line with the expectation,and has the feasibility of engineering.
