AMI lightweight data privacy protection method oriented to electric power internet of things

Abstract

The invention discloses an AMI lightweight data privacy protection method for the electric power Internet of Things. The method comprises the steps that a cloud-side-end AMI system architecture is constructed; multi-level anonymous access authentication of end equipment such as an intelligent electric meter is realized under the architecture of a cloud -side -end AMI system, and the intelligent electric meter is dynamically managed by dynamically accessing an Internet of Things proxy terminal through a plug-and-play information model under the same security computing environment; and safe transmission of data in the AMI system is realized through a lightweight data aggregation privacy protection method. The embodiment of the invention is based on a multi-level anonymous authentication mode, and re-authentication is not needed when end equipment such as an intelligent electric meter is accessed to the system, so that the access complexity of the end equipment is reduced, and meanwhile,the access security is ensured.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an AMI lightweight data privacy protection method oriented to the electric power Internet of Things. Background technique [0002] The Advanced Measurement Infrastructure (AMI) system collects electricity data from user-side smart meters, performs data analysis and diagnosis, and realizes status monitoring of meters in the grid and metering of user electricity consumption. With the advancement of the construction of the electric power Internet, the business requirements for public utility data collection, distributed power supply access and monitoring, charging pile data collection, demand-side data collection, enterprise energy efficiency monitoring, and smart home applications have increased, making the AMI system architecture also toward The development in the direction of "cloud-edge-end" has introduced more IoT proxy terminals and various types of sensing devices. A...
