Privacy protection method based on power injection under ami and 5G smart grid

Abstract

The invention discloses a privacy protection method based on power injection under AMI (Advanced Metering Infrastructure) and a 5G smart power grid. The method comprises the steps that a power company initializes a system, selects random parameters from a finite field, generates a private key and discloses a series of parameters; communication between the power company and storage units is carried out through a gateway, the power company generates feature parameters through utilization of one-way hash functions, establishes single-use keys, places the single-use keys into request packets and sends power purchasing requests to the gateway, and after the gateway checks the request packets, the gateway broadcasts the request packets to the storage units; after the storage units receive the request packets, the storage units cover bidding through hash point addition according to the single-use keys and generates information verification codes; response packets are returned to the gateway; the gateway collects all response packets, aggregates bidding and information verification codes and sends the biding and information verification codes to the power company; and the power company carries out unpackaging through utilization of the private key to obtain the bidding. According to the method, the privacy of a user is protected, the confidentiality of the user is protected, the occupation of the bandwidth is reduced, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, and in particular relates to a privacy protection method based on AMI and power injection under 5G smart grid. Background technique [0002] The Internet of Things refers to a huge network formed by combining various information sensing devices with real-time collection of any required information such as objects or processes that need to be monitored, connected, and interacted with the Internet. With people, all items are connected to the network, which is convenient for identification, management and control. As an important part of the new generation of information technology, it occupies an increasingly important position in our daily life. With the continuous change of technology and the lack of security and update mechanism, IoT devices have gradually become the main force of botnets: in October 2016, the United States suffered the most serious DDoS attack in history, c...
