摘要
电表数据经数据采集器采集、数据聚合器收集后传输给数据存储中心,而当前的用电数据采集方法存在数据泄露、中间人攻击,且攻击者不易被发现等风险。针对这一系列问题,提出了RAHRM的方法,采用RSA AES HASH签名认证,并采用RSA对智能电表传输的数据进行加密,同时对服务器端进行流量监控和异常报警,为电表数据传输提供一个安全、可靠的通道。实验结果表明,此电表数据采集方法可以降低智能电表通信中的中间人攻击与攻击者不易被发现的风险,保证通信线路的安全。
The data of the meter is collected by the data collector and data aggregator,which is transmitted to the data storage center.The current method of collecting electricity data has data leakage,man-in-the-middle attacks,and the problem that attackers are not easy to find.To solve this problem,a method called RAHRM is proposed,adopting RSA AES HASH authentication.In the authentication process,the information is summarized by the HASH function,and the data transmitted by the smart meter is encrypted,using RSA encryption algorithm.At the same time,traffic monitoring and abnormal alarm on the server.Praide a safe and reliable channel eusuring the need for real-time intelligent data collection of smart meters.The experimental results show that this security protection method can reduce the man in the middle attacks in the process of smart meter communication and solve the problem that attackers are not easy to be discovered.It can ensure the safety of communication lines.
