Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 and figure 2 As shown, an information sharing blockchain partition method is implemented based on geographic location in the Internet of Vehicles environment, specifically:

[0042] 1. System initialization.

[0043] In the initialization phase, the trusted organization generates parameters for the entire system and all RSUs (Road-SIDEUNIT, hereinafter referred to as RSU). RSUs need to obtain permission before joining the blockchain architecture. After registration, the geographic location information is sent to the information center for subsequent balanced clustering operations.

[0044] The above step 1 specifically includes:

[0045] The initialization parameters are generated by TA (TRUSTED AUTHORITY, hereinafter referred to as TA), and two groups G and G that satisfy the bilinear mapping are selected. T (G×G→G T ), ...

Abstract

The invention relates to an information sharing block chain partitioning method, system and device and a storage medium. The method comprises the following steps: S1, a trusted mechanism generates an initialization parameter, and road side units upload geographic position information to an information center and form a set; S2, balanced clustering is carried out, and zoning planning is carried out on road side units; S3, a node with the maximum right value in the road side units is selected as a leader, and the other road side units are taken as slave nodes; S4, a leader receives a command for sending a broadcast request and sends broadcast messages to the slave nodes; S5, each slave node verifies the broadcast message, broadcasts the message after successful verification, and feeds back response information to the leader; and S6, the leader judges whether the same response number of each slave node exceeds a preset threshold, and if yes, the response information is recorded and linked. According to the invention, the problems of centralization and mutual distrust among entities of a traditional centralized Internet of Vehicles architecture and the problems of high delay and poor expandability of a traditional block chain architecture can be solved, and the performance loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of block chain, and in particular relates to an information sharing block chain partition method, system, equipment and storage medium. Background technique [0002] As part of an intelligent transportation system, the Internet of Vehicles can improve road safety, increase traffic flow and reduce congestion through the sharing of traffic information among vehicles. However, if the traffic information sent by the vehicle is lost or tampered with during the journey, it will affect the driver's decision-making, leading to serious deviations from the route, and even threatening the safety of the vehicle or the driver. [0003] In the Internet of Vehicles system, the traditional architecture mainly includes vehicles, road-side units (Road-Side Unit, hereinafter referred to as RSU), certificate authority (Certificate authority, hereinafter referred to as CA), and core network. The information is collected by the ...
