Fig. 1 is a schematic diagram of a system for securing information in a vehicle networking according to an embodiment of the present disclosure. The system comprises:
the method comprises the following steps of (1) trappingnodes 101, a vehiclenetworking protection platform 102, asimulation trapping background 103 and asimulation vehicle machine 104;

the trappingnode 101 establishes communication connection with thesimulation trapping background 103 through a second network channel to acquire the information of the simulation vehicle machine;
the trappingnode 101 establishes communication connection with the internet ofvehicles service platform 20 through a first network channel, so that the trappingnode 101 sends simulated vehicle machine information to the internet ofvehicles service platform 20 through the first network channel and receives attack information from the first network channel, and the second network channel is a network channel isolated from the first network channel;
the trappingnode 101 further establishes a communication connection with the internet ofvehicles protection platform 102 through a second network channel, so that the trappingnode 101 sends the attack information to the internet ofvehicles protection platform 102 through the second network channel.

The trapping nodes and the simulation trapping background are decoupled, so that one simulation single board can simulate a plurality of trapping nodes, the requirement on running resources is low, and the cost is greatly saved.
In this embodiment, the captive node may have a SIM (Subscriber Identity Module) or form a SIM network together with the SIM, so that the captive node may access the car networking service platform through the beacon, and this channel may serve as the first network channel.
In this specification, the car networking service platform may be deployed in a cloud server, and is not specifically described herein.
