Abstract

The invention discloses an intelligent power grid data aggregation and encryption method with forward security. The method comprises: a key generation center KGC generating an initial private key andsending the initial private key to an intelligent electric meter through a secret channel; the intelligent electric meter verifying the initial private key, encrypting and signing the data of the userto generate a signature private key, sending the signature private key to the aggregation gateway, and updating the signature private key; the aggregation gateway aggregating the received signature private keys to generate an aggregation signature and sending the aggregation signature to the control center; and the control center verifying the aggregated signature, and decrypting and decoding theaggregated signature by using the private key k encrypted by the public key to obtain a plaintext m after successful verification. The problems of plaintext transmission of user power consumption information data and the like, data transmission congestion from the intelligent electric meter to a control center and expenditure in an existing aggregation encryption algorithm in an existing intelligent power grid are solved. The method is suitable for encrypting and aggregating the transmission data of the intelligent power grid, and the purpose of safely and efficiently transmitting the data isachieved.

Description

technical field [0001] The invention relates to the technical field of smart grid security, and more specifically relates to a smart grid data aggregation and encryption method with forward security. Background technique [0002] At present, with the rapid development of my country's economy and network technology, my country's demand for all aspects of the power system is constantly increasing, and the process of intelligence is also advancing. At the same time, the security issues of smart grids are also receiving increasing attention. There is a large-scale automatic control management system in the smart grid, which is composed of many control centers, users and various equipment. Each of these control centers manages the power grid in a corresponding area, including various devices and users in this area. Various sensors and smart meters equipped in the power grid are responsible for real-time monitoring of the operating status of the power grid and collection of user ...
