Homomorphic encryption based security data fusion technology of smart grid

针对目前智能电网隐私保护技术尚无法提供足够的效率和安全特性这一问题,设计了一种安全有效的智能电网安全数据融合方案。该方案在确保用户的数据前向安全的前提下,采用签名融合技术减少了计算开销。研究了智能电网安全数据融合方案的实现方法并对方案进行了安全分析及性能分析,最后在Simple WSN平台上进行了系统仿真实验,实验结果表明,该方案具有可行性,适用于智能电网中。

Since the available privacy protection technology of the smart grid is unable to provide enough efficiency and security feature,a safe and effective security data fusion scheme of the smart grid was designed. On the premise of ensuring the user′s data forward security,the signature fusion technology is used to reduce the computing cost. In this paper,the implementation method of the security data fusion scheme of the smart grid is studied,and its security analysis and performance analysis are performed. The system simulation experiment was conducted on Simple WSN platform. The experimental results show that the scheme is feasible,and is suitable for smart grid.
