Electric power data aggregation collection method and device, computer equipment and storage medium

Abstract

The invention relates to an electric power data aggregation collection method and device, computer equipment and a storage medium, and the method comprises the steps: setting and initializing system parameters, so as to obtain a public key and a private key of an intelligent electric meter, calculating the public key and the private key, and collecting the public key and the private key; creatingan area to obtain an area common public key; acquiring the power consumption quantity of the intelligent electric meter encrypted by adopting an addition homomorphic encryption technology to obtain adata packet; calculating a label parameter of the data packet to obtain a first label parameter; judging whether the data packet is calculated by the intelligent electric meter or not by adopting thefirst label parameter; if so, performing aggregation processing on the data packet to obtain an aggregated data packet; calculating a label parameter of the aggregated data packet to obtain a second label parameter; judging whether the aggregated data packet meets the requirement or not by adopting a second label parameter; and if so, processing the aggregated data packet to form power data. Userprivacy is prevented from being invaded, the reliability of the power data transmission process is improved, and the user privacy protection effect is improved.

Description

technical field [0001] The present invention relates to smart grid security information, and more specifically refers to a power data aggregation collection method, device, computer equipment and storage medium. Background technique [0002] Smart city refers to the use of technologies such as the Internet of Things, 5G communications, cloud computing and big data processing to integrate, coordinate and integrate various resources or systems in the city to improve resource utilization and urban operation efficiency, and strengthen urban management and service capabilities. , to further improve the quality of urban development and the living standards of residents. Smart city construction can be subdivided into various branches of the city, such as transportation, supply and management of water and electricity resources, government services, medical security, and public safety maintenance. The fundamental factors that promote the reliable operation of smart cities in various...

Problems solved by technology

However, power companies and government departments only need to know the total electricity consumption of the city in each time period, and the electricity consumption of each user in each time period should only be known by the user, otherwise, the user's privacy may be compromised. Leakage, and therefore suffered losses, and the current security protection mechanism for power data is encrypted with the same key when aggregating power data, and does not take into account the threat brought by internal malicious users, which makes the use of traversal snooping inside the smart grid Electricity data of other users of the smart grid becomes possible, therefore, the privacy protection effect is weak
