Embodiment Construction

[0059] The Internet of Things (IoT) is the Internet that connects things and things. It uses communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things together in a new way to form people and things, Things are connected to each other to realize 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 Internet applications, but all elements in the Internet of Things (including all equipment, resources, and communications, etc.) 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 also different. The traditional definition of Internet of Vehicles refers to the electronic tags loaded on vehicles through...

Abstract

The embodiment of the invention provides a communication method, a communication device, a server and a system. The method is applied to the communication device, the communication device is configured with control rule parameters, and the control rule parameters comprise a signature verification rule parameter, a message aggregation rule parameter and a report control rule parameter. The method comprises the following steps: receiving a 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; and sending a second message to the server according to the message reporting control rule parameter, wherein the second message is a message obtained by performing signature verification processing and message aggregation processing on the first message. The problem that signature verification cannot be carried out on the message in time due to insufficient RSU performance is solved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a communication method, communication device, server and system. Background technique [0002] In the existing technical solutions, 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 vehicles, roadside equipment, equipment carried by pedestrians, and the Internet. [0003] For the sake of security, the broadcast message sent by OBU is usually encrypted and signed broadcast message. After receiving the broadcast message sent by OBU, RSU needs to perform two signature verifications to verify the authenticity of the broadcast message. In the prior art, the processing speed of the RSU to verify the signature of the broadcast message is far from meeting th...
