智能电网集成了通信网络,并设有智能电表等远程终端,使得电网控制中心与远程终端之间能够双向通信,实现了电能的优化传输与配送。然而智能电网实时采集数据的汇聚效应会导致网络拥塞,并带来用户的隐私保护问题。结合智能电网中网络与设备的特点以及隐私保护与安全需求,基于假名、同态加密和基于身份的聚合签名技术,本文提出了一个智能电网通信中的聚合方案,解决了远程终端向电网控制中心发送海量数据的隐私保护与安全通信问题。经过安全性与性能分析,本文方案满足智能电网通信的安全性与性能需求。
The smart grid integrates the communication network and has remote terminals such as smart meters to enable two-way communication between the grid control center and the remote terminals to achieve optimized transmission and distribution of electric energy. However, the gathering effect of real-time collected data in the smart grid will lead to network congestion and user privacy protection. Combined with the characteristics of networks and devices in smart grid and the requirements of privacy protection and security, based on the pseudonym, homomorphic encryption and identity-based aggregation signature technology, this paper presents an aggregation solution in smart grid communication, which solves the problem that the remote terminal sends a message to the grid control center Sending privacy protection and secure communication of massive data. After security and performance analysis, this program to meet the security requirements of smart grid communications and performance requirements.
