基于IEC61850的智能变电站数据隐私保护方法研究

Smart Substation Data Privacy Protection Method Based on IEC61850

作为能源互联网发展的重要组成部分,基于IEC61850协议的智能变电站能够满足不同智能设备对于上层协议的一致性。然而,在智能变电站中存在网络安全及数据泄露隐患。例如数据恶意注入、窃听、篡改、非法截获等外部攻击都是破坏智能变电站稳定运行的隐患。针对智能变电站网络安全及数据隐私保护需求,提出了基于数据聚合的轻量级数据隐私保护方案。安全性分析和仿真实验表明,所提方案既能满足智能变电站数据隐私保护需求,也能满足智能变电站的网络通信性能要求。

As an important part of the development of energy Internet,smart substation based on IEC61850 protocol can meet the consistency of different intelligent devices for upper layer protocols.However,there are hidden dangers of network security and data leakage in intelligent substations.For example,external attacks such as malicious data injection,eavesdropping,tampering and illegal interception are all hidden dangers of the stable operation of smart substations.In the light of the security requirements of smart substation communication and the requirement of real-time communication,a lightweight data privacy protection scheme is proposed based on data aggregation.Security analysis and simulation experiments show that the proposed scheme can not only meet the data privacy protection requirements of intelligent substation,but also meet the network communication performance requirements of intelligent substation.
