Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, and Not all examples.

[0030] Such as figure 1 As shown, an anonymous authentication system based on anti-tampering equipment in a smart grid includes an operation center of the smart grid, a residential area gateway, and a smart meter; the residential area gateway is used to connect the operation center and the smart meter; the operation center uses for generating system public security parameters; the smart meter includes a tamper-resistant device. When the smart grid system is initialized, the operation center generates public parameters according to the security parameters, and exposes the public parameters to the...

Abstract

The invention belongs to the field of power data security transmission in an intelligent power grid environment, and particularly relates to an anonymous authentication method and an anonymous authentication system based on tamper-proof equipment in a intelligent power grid. The anonymous authentication method comprises the steps that: an operation center of the intelligent power grid generates system public parameters according to safety parameters and distributes the system public parameters to intelligent electric meters and residential district gateways; the intelligent electric meter collects real-time electric power data, encrypts the electric power data by adopting an addition homomorphic encryption algorithm, signs the electric power data by using a private key of the intelligent electric meter, and sends a signed electric power data ciphertext to the residential district gateway; the residential district gateway authenticates the ciphertext after receiving the ciphertext, performs privacy protection aggregation on the ciphertext if the authentication succeeds, and sends an aggregated ciphertext signature to the operation center; and the operation center verifies the validity of a timestamp and a signature of the operation center, if the verification is valid, the aggregated ciphertext is decrypted by adopting the private key, and a plaintext message of the power data is obtained. According to the anonymous authentication method and the anonymous authentication system, the safety of the intelligent power grid system is greatly improved.

Description

technical field [0001] The invention belongs to the field of data security in the discipline of computer information security, and in particular relates to the problem of safe transmission of electric power data in a smart grid environment, specifically an anonymous authentication method and system based on a tamper-proof device in a smart grid. Background technique [0002] As a next-generation power system, the smart grid integrates power transmission and information transmission. With the increasing demand for electricity, it is necessary for the traditional power system to evolve into a smart grid system in order to solve the optimization and integration of power resources and effectively solve the peak power consumption situation. A smart grid is actually an enhancement of traditional grid technologies. While traditional grids are typically used to deliver electricity from a small number of central generators to a large number of users or customers, smart grids use bid...
