ONE-WAY GATEWAY, VEHICLE NETWORK SYSTEM AND METHOD FOR PROTECTING NETWORK WITHIN VEHICLE USING ONE-WAY GATEWAY

摘要

PROBLEM TO BE SOLVED: To present a one-way gateway that applies a limited physical one-way communication technology to the internal network and infotainment network of a vehicle, thereby fundamentally blocking a threat intended to illegitimately control a vehicle through external malicious behavior and also smoothly providing existing associated information, and a vehicle network system and method for protecting networks within a vehicle using the one-way gateway.SOLUTION: The vehicle network system comprises: an internal network of a vehicle; an infotainment network of the vehicle; and a one-way gateway configured to perform only transmission of data from the internal network to the infotainment network through one-way communication, to receive a request transmitted from the infotainment network to the internal network, and to transmit only a normal request to the internal network.SELECTED DRAWING: Figure 2
