A one-way gateway and a vehicle network system and method for protecting networks within a vehicle using the one-way gateway. The one-way gateway includes a communication control unit, a physical one-way communication unit, and a data transmission/reception unit. The communication control unit takes charge of communication with a device of the internal network or infortainment network of a vehicle. The physical one-way communication unit configures a communication section between the internal network and the infortainment network in a physically one-way form. The data transmission/reception unit transfers data, transmitted by the device of the internal network or infortainment network, to the physical one-way communication unit via the communication control unit, and transfers data, received via the physical one-way communication unit, to the device of the internal network or infortainment network.

A physical unidirectional communication apparatus and method intended to utilize a structure that exploits an electrical signal by which data cannot be transmitted and to guarantee the reliability of data transmission via a transmission method that uses the structure. The physical unidirectional communication apparatus includes a unidirectional data transmission line, a data reception status transmission line, an internal network connection system unit for performing communication with an internal network transmission host and transmitting transmission data to an external network connection system unit through the unidirectional data transmission line, and the external network connection system unit for performing communication with an external network reception host, receiving the transmission data from the internal network connection system unit, generating reception status information of the transmission data, and transmitting the reception status information to the internal network connection system unit through the data reception status transmission line.

An out-of-vehicle device interface apparatus includes a request message reception unit, a response message request unit, and a response message transmission unit. The request message reception unit receives a request message from an out-of-vehicle device, generates electrical signals in electric lines, and transfers the request message. The response message request unit requests response messages for the request message from one or more devices constituting an in-vehicle network based on one or more of the electric lines in which electrical signals have been generated. The response message transmission unit receives the response messages from the one or more devices, and transfers the response messages to the out-of-vehicle device via unidirectional communication.
