Problems solved by technology

[0003] However, the existing smart grid also has certain problems in terms of communication security and privacy protection
On the one hand, as a communication network system, the smart grid will also face security risks of other communication network systems
Forged identities and tampered data will mislead system decisions and cause system damage, resulting in economic losses
On the other hand, high-frequency electricity consumption data will leak user privacy, which will cause safety issues for the life and property of electricity users, such as advertising push, burglary, etc.

Embodiment Construction

[0034] 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.

[0035] At first, some concepts mentioned in the present invention are introduced as follows:

[0036] Let k be a constant and p be a prime number of length k. is a ring of order p. G and G T are two groups of order p. G is an additive group, G T is a multiplicative group. If a function e: G×G->G T Satisfies the following conditions, then e is a bilinear pairing.

[0037] Bilinear: for all P ∈ G, e(aP, bP) = e(P, P) ab ;

[0038] Non-degenerate: sin...

Abstract

The invention discloses a smart grid system based on batch sign encryption and its construction method. The user report is protected by a key. As long as the key is not disclosed, the user's electricity consumption data will not be tampered with or leaked during the transmission process. , the integrity and validity of electricity consumption reports are guaranteed, which can solve the problems of communication security and privacy protection in smart grids. In addition, in the technical solution provided by the present invention, a tree topology is used to collect power consumption data, and the computing cost of the power supplier is distributed to each smart meter. In addition, the technical solution provided by the present invention constructs a signcryption scheme without a random oracle, and each smart meter uses a constant level of calculation to verify multiple signcryptions. Moreover, the smart meter generates a new signature and ciphertext by simply adding the signature and the key, and no longer needs re-encryption and re-signature with a large amount of calculation, thereby reducing the calculation time of the system.

Description

technical field [0001] The invention relates to the technical field of smart grids, and more specifically relates to a smart grid system based on batch signcryption and a construction method thereof. Background technique [0002] Through the comprehensive use of communication technology, sensor technology, automation technology and power grid infrastructure, the smart grid can obtain the panoramic information of the power system, which can not only detect, predict and self-repair power failures in time, but also improve the utilization rate of power equipment and reduce power consumption. , thereby greatly improving the operating efficiency of the power grid. High-frequency power consumption data collection is used to control the power supply and power consumption ends, strengthen the power carrying capacity, and thus improve the optimal allocation of energy resources in the power grid. [0003] However, the existing smart grid also has certain problems in terms of communic...
