一种针对智能电表DL/T 645—2007协议的中间人攻击

An Intermediate Attack Against Smart Meter DL/T 645—2007 Protocol

利用协议的攻击实验分析和改进协议的安全性,确保智能电表通信安全.首先在熟悉通信协议的基础上,挖掘其存在的漏洞;然后实施arp欺骗,伪造成中间人嗅探电表与采集终端的通信流量,达到篡改电能数据的目的.实验表明,协议的脆弱性会带来中间人篡改数据的风险,最终威胁智能电表的信息安全.

Protocol attack experiments are used to analyze and improve the protocol security so as to ensure the communication safety of smart meters. Firstly, on the basis of understanding the communication protocol, its loopholes are tapped, and then ARP spoofing is implemented to induce the communication flow between the sniffer and the acquisition terminal, and to achieve the pur- pose of tampering with electric energy data.
