Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] The present invention proposes a smart grid data aggregation and encryption method with forward security, the method can use the national secret SM2 elliptic curve public key encryption algorithm to realize the encryption of electricity data, and can be used without bilinear pairing In this case, the forward security theory and strong RSA assumption are used to dynamically update the signature private key with different time periods, and delete the signa...

Abstract

The invention discloses a smart grid data aggregation and encryption method with forward security. The key generation center KGC generates an initial private key and sends it to a smart meter through a secret channel; the smart meter verifies the initial private key, and the user's data Implement encryption and signature to generate a signature private key, send it to the aggregation gateway, and update the signature private key at the same time; the aggregation gateway aggregates the received signature private key to generate an aggregate signature and send it to the control center; the control center verifies the aggregate signature, After the verification is successful, the aggregate signature is decrypted and decoded with the private key k encrypted with the public key to obtain the plaintext m. The invention solves the problem of plaintext transmission of user electricity information data in the existing smart grid, data congestion in the transmission from the smart meter to the control center, and overhead problems in the existing aggregation encryption algorithm, and is suitable for data transmission in the smart grid. Encryption and aggregation to achieve the purpose of safe and efficient data transmission.

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 ...
