Embodiment Construction

[0059] The Internet of Things (IoT) is the Internet where things are connected to each other. It uses communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things in a new way to form people and things. Connecting things to things, realizing informatization, remote management control and intelligent network. The Internet of Things is an extension of the Internet. It includes the Internet and all resources on the Internet, and is compatible with all applications on the Internet. However, all elements in the Internet of Things (including all devices, resources, and communications) are personalized and privatized.

[0060] The concept of the Internet of Vehicles is derived from the Internet of Things. According to different industry backgrounds, the definition of the Internet of Vehicles is not the same. The traditional definition of the Internet of Vehicles means that the electronic tags loaded on vehicles can ext...

Abstract

The embodiment of the present application provides a communication method, communication device, server and system, the method is applied to the communication device, the communication device is configured with control rule parameters, and the control rule parameters include signature verification rule parameters, message aggregation rule parameters and reporting control Rule parameter; the method includes: receiving the first message; performing signature verification processing on the first message according to the signature verification rule parameter, and performing message aggregation processing on the first message after signature verification processing according to the message aggregation rule parameter; reporting according to the message The control rule parameter sends a second message to the server, and the second message is a message obtained after performing signature verification processing and message aggregation processing on the first message. Fixed an issue where signature verification of messages could not be performed in a timely manner due to insufficient RSU performance.

Description

technical field [0001] The present application relates to the field of communication, and in particular, to a communication method, communication device, server and system. Background technique [0002] In the prior art solution, the periodic or event-triggered broadcast messages of the on-board-unit (OBU) of the connected car can be aggregated by the road side unit (RSU), and then uploaded to the The V2X (Vehicle-to-Everything) server performs subsequent analysis and processing. Among them, X can be a vehicle, a roadside device, a device carried by a pedestrian, and the Internet. [0003] For security reasons, the broadcast message sent by the OBU is usually an encrypted and signed broadcast message. After the RSU receives the broadcast message sent by the OBU, it needs to perform two signature verifications to verify the authenticity of the broadcast message. In the prior art, the processing speed of the RSU for verifying the broadcast message is far from the speed at wh...
