Embodiment Construction

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Such as figure 1 As shown, the software security upgrade method based on V2X roadside equipment of the present invention comprises the following steps:

[0026] 1) Based on the SSL / TLS secure transmission protocol, RSU establishes a secure authentication and secure connection with the Internet of Vehicles cloud platform and the Internet of Vehicles cloud platform, and registers device information;

[0027] 2) Regularly query the cloud platform for the version number of the Internet of Vehicles software that the roadside equipment is running;

[0028] 3) RSU compares the queried application version number with the locally running application version number. If the queried version number is relatively new, RSU applies for software upgrade to the cloud platform;

[0029] 4) The cloud platform sends the software upgrade package to the ...

Abstract

The invention relates to a software security upgrading method and system based on V2X roadside equipment, and belongs to the technical field of Internet of Vehicles. The method comprises: an RSU establishing an SSL safety connection with an Internet of Vehicles cloud platform, and registers equipment information to the cloud platform; after the safe connection is established, periodically inquiring the version number of the Internet of Vehicles software of the roadside equipment from the cloud platform; The RSU compares the queried application version number with the local running applicationversion number, and if the queried version number is new, the RSU applies for software upgrading to the cloud platform; the cloud platform sending a software upgrade package to the RSU, and the RSU performs integrity verification on the upgrade package; and after it is determined that the upgrade package is complete, the RSU backs up the old version installation package and runs the new version software. The system comprises an Internet of Vehicles cloud platform, roadside equipment and an application storage server. The RSU is remotely upgraded on the basis of the security protocol, so that the maintenance and upgrading cost of the roadside equipment system is reduced, and the upgrading security is ensured.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and relates to a method and system for safely upgrading software based on V2X roadside equipment. Background technique [0002] With the rapid increase of car ownership, problems such as road safety and urban congestion are becoming more and more serious. V2X Internet of Vehicles technology can realize all-round connection between vehicles and vehicles, pedestrians, traffic infrastructure and cloud platforms, including vehicle-to-vehicle (V2V), vehicle-to-roadside equipment (V2I), vehicle-to-pedestrian and other vulnerable traffic participants (V2P ), vehicle-to-cloud platform (V2N), etc., to improve traffic efficiency and driving safety. [0003] In the V2X Internet of Vehicles system, roadside equipment is deployed at intersections and important special road sections, communicates with vehicles equipped with V2X communication equipment, and provides real-time road traffic informat...
