Description

Vehicle networking verification method, device and vehicle networking system

Technical field

The present invention relates to the field of the Internet, and in particular, to a vehicle networking verification method, device, and vehicle networking system.

Internet of Vehicle (IoV) is an emerging network based on Internet, Internet of Things and software technology. Specifically, the Internet of Vehicles is based on vehicles as nodes and information sources, using network technology and wireless communication technologies. The network of “people-car-road-environment-society” achieves the purpose of identifying, locating, tracking, supervising and pushing services.

The current car network uses D2D (Device to Device Communication, D2D) communication technology. D2D technology is a technology that can directly communicate between terminal devices under the control of a base station (eNB). In the prior art, when the terminal device logs into the car network, the car network does not verify the identity of the terminal device, so the D2D-capable terminal device can log in to the car network and use the resources provided by the car network.

The disadvantage of the prior art is that after the terminal device of the non-vehicle network is logged into the car network, it may occupy a large amount of resources provided by the car network, and the resources available to the car network terminal device are reduced, which may cause the communication delay between the car network terminal devices to be changed. Big. In addition, non-vehicle networked terminal devices have low security performance and are easily exploited by hackers to send a large amount of redundant information or malicious attack information inside the car network, resulting in a decrease in the speed of the car network communication and even a paralysis of the car network, which may also cause a car.
