A lightweight preserving-privacy scheme with authentication in Energy Internet

Energy Internet is considered as a promising approach to solve the problems of energy crisis and carbon emission. In Energy Internet real-time usage data are collected for optimizing the energy utilization. However, data malicious injection, eavesdropping, tampering, illegal interception, etc. are potential dangers that undermine the stable operation of energy interconnection. To cope with the security requirements of the Energy Internet and the requirements for real-time communication, as well as the complex architecture of the energy system, a lightweight data privacy protection scheme based on data aggregation is proposed to achieve device data privacy protection while achieving mutual authentication between devices , Improve the performance of the algorithm on the basis of meeting the security requirements, and prove its security and efficiency through security analysis and cost analysis to meet the network communication requirements of the Energy Internet.
