Method and system suitable for intelligent power utilization data aggregation

Abstract

The invention discloses a method and a system suitable for intelligent power utilization data aggregation, and belongs to the technical field of information security. The method comprises the steps that a trusted third party generates initialization parameters of an intelligent electric energy meter and a convergence terminal, and the intelligent electric energy meter and the convergence terminal are controlled to use the initialization parameters to complete initialization; after the intelligent electric energy meter and the convergence terminal are initialized, the intelligent electric energy meter is registered to the convergence terminal and the trusted third party, the convergence terminal is registered to the control center and the trusted third party, and the control center is registered to the trusted third party; after registration is completed, the intelligent electric energy meter sends user data to the convergence terminal, the convergence terminal obtains a user ID according to the user data and sends the user ID to the control center and the trusted third party, and the trusted third party generates a blinding factor according to the user ID and transmits the blinding factor to the convergence terminal through the control center; and the aggregation terminal aggregates the user data according to the blinding factor. The invention has a fault-tolerant mechanism and can protect data privacy.

Description

technical field [0001] The present invention relates to the technical field of information security, and more specifically, relates to a method and system suitable for aggregation of intelligent electricity consumption data. Background technique [0002] Smart grid is an automated and intelligent new grid formed by combining computer network and information infrastructure. On the one hand, smart grid has the characteristics of inclusiveness, interaction and openness. Power users can participate in grid operation more widely through smart meters. Grid and The two-way interaction of power users is more frequent, and the experience of power users has been greatly improved. On the other hand, the smart grid has the characteristics of a large number of users, strong two-way interaction, and complex network boundaries. Its openness and inclusiveness also pose challenges to the safe and reliable operation of the smart grid and the privacy protection of power users. In the smart gr...

Problems solved by technology

Most of the existing privacy protection and data security aggregation technologies are implemented based on homomorphic encryption algorithms, which will bring large computing overhead, and relatively little consideration is given to the fault tolerance of data aggregation, and are not suitable for intelligent power consumption information systems. Privacy protection and aggregation analysis and processing of electricity data, so it is urgent to study the safe and efficient aggregation method of intelligent electricity consumption data that supports fault tolerance and privacy protection, and improve the overall security of the intelligent electricity consumption information system
