Abstract

The invention discloses a data privacy protection method for intelligent electric meters, and the method comprises the steps: dividing a plurality of intelligent electric meters into a plurality of electric meter groups according to a preset strategy, distributing different group keys for each electric meter group, and enabling each intelligent electric meter to have a unique and fixed original user ID; Each intelligent electric meter in the current electric meter group generates a plurality of pseudo user ID sequences with different combinations according to the group key and the time, and selects different pseudo user ID sequences at different times, and the number of the pseudo user IDs in the pseudo user ID sequences is not less than the number of the intelligent electric meters in thecurrent electric meter group; And each intelligent electric meter in the current electric meter group selects different pseudo user IDs from the currently selected pseudo user ID sequence to replacethe original user ID in the data packet, and sends the data packet. The power utilization privacy of the user can be protected.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a data privacy protection method of a smart meter. Background technique [0002] The smart grid is an enhancement technology to the traditional grid. While traditional electricity networks are used to deliver electricity from central generators to thousands of consumers, smart grids use bi-directional flow of electricity and information to create automated and distributed advanced energy transmission networks with self-healing , high reliability, high power quality, resistant to network attacks, adaptable to various distributed power generation and storage devices, etc., by using modern information technology, the smart grid can transmit power in a more efficient way, and control various event in response. A smart grid can respond to events occurring anywhere in the grid, such as generation, transmission, distribution, and consumption, and be able to take appropriate ac...
