在电网中部署相量测量单元（PMU）将增强对电网运行的实时监测和分析。PMU收集母线电压相量、分支电流相量和母线频率测量值，并使用通信网络将测量值传输到相应的变电站/控制中心。PMU信息是敏感的，因为丢失或不正确的PMU数据可能导致电网故障和/或损坏。重要的是使用加密的通信信道来避免网络攻击。在这项研究中，侧信道攻击使用数据包间延迟隔离的数据包流的一个PMU从加密的隧道。此外，电力系统VPN的加密和脆弱性，由于侧信道分析进行了讨论。
The deployment of Phasor Measurement Units (PMUs) in an electric power grid will enhance real-time monitoring and analysis of grid operations. The PMU collects bus voltage phasors, branch current phasors, and bus frequency measurements and uses a communication network to transmit the measurements to the respective substation(s)/control center(s). PMU information is sensitive, since missing or incorrect PMU data could lead to grid failure and/or damage. It is important to use encrypted communicate channels to avoid cyber attacks. In this study, a side-channel attack using inter-packet delays to isolate the stream of packets of one PMU from an encrypted tunnel is shown. Also, encryption in power system VPNs and vulnerabilities due to side channel analysis is discussed.
