目前电力远程抄表系统中数据的安全问题没有引起足够重视,数据的传输普遍以明文形式进行。为了保证数据传输的安全性以及提高AES算法在电力远程抄表系统中的执行效率,对AES算法的加密和解密进行改进,并利用改进后的算法对数据进行加密。既保证了数据传输的安全性又提高了系统的工作效率。具有需求空间小、密钥管理方便、运行速度快等优点,非常适合电力远程抄表系统中数据的加密。
At present, the problem of data security in the power remote meter reading system has not been given sufficient attention. Data transmission is generally conducted in plaintext. In order to ensure the security of data transmission and improve the efficiency of AES algorithm in power remote meter reading system, the encryption and decryption of AES algorithm are improved and the data is encrypted by the improved algorithm. This not only ensures the safety of data transmission but also improves the work efficiency of the system. With the advantages of small space requirement, convenient key management and fast operation, it is very suitable for data encryption in power remote meter reading system.
