Method for providing a communication channel for secure management between a physically separated uniway data transmitting and receiving device in uniway security gateway system and uniway data transmitting and receiving device providing two uniway communication channels therefor
Disclosed are a method for providing a secure management communication channel between a physically isolated one-way data transmission device and a receiving device in a one-way security gateway system, and a one-way data transmission/reception device providing two one-way communication channels for the same. A one-way security gateway system according to an embodiment includes a one-way data transmission device located in a security area and a one-way data reception device located in a control area, and the one-way data transmission/reception device transmits and receives one-way data from the security area to the control area. It provides a first communication channel for unidirectional transmission and reception of management data from the control area to the security area.
