针对智能电表嵌入式工程文件的保密性问题,提出了一种基于椭圆曲线的快速智能电表嵌入式工程文件加密和解密方法。首先对智能电表嵌入式工程文件的预处理,通过转化嵌入式工程文件为数字符号,再利用椭圆曲线加密预处理的基础上对智能电表软件工程文件进行加密和解密的操作。论文通过减小密钥的数据长度以及重定义工程文件中的高频词汇的加密值,降低了加密的时间消耗和资源消耗,减小了加密计算量,提高了加密速度。

Aiming at the security problem of embedded engineering file of smart meter,this paper puts forward a method of fast and intelligent embedded engineering file encryption and decryption based on elliptic curve.Firstly,the pretreatment of the smart meter embedded engineering documents has been taken,and then through turning embedded project file into the number symbols,the encryption and decryption of the smart meter software project file will be taken based on elliptic curve encryption preprocessing.By reducing the data length of the key and redefining the encryption value of the high frequency words in the project file,the time consumption and resource consumption are cut down,the amount of encryption computation is reduced,and the encryption speed is improved.
