UNIDIRECTIONAL DATA TRANSMISSION SYSTEM

Номер: KR101870318B1
Принадлежит: NNSP CO., LTD.

The present invention provides a unidirectional data transmission system which can notify information that an error occurs on a receiving side from a receiving device to a transmitting device while maintaining a structural property of the unidirectional data transmission system. The unidirectional data transmission system comprises the transmitting device and the receiving device. The transmitting device monitors a data line and a state information line, collects data from a first server through a first network when the error of the receiving side is not detected, and transmits the collected data through the data line. The receiving device transmits the data received through the data line to a second server through a second network when the error of the receiving side does not occur, and performs switching of the data line, switching of the state information line or switching and connection operation of the state information line when the error of the receiving side occurs.

INTER-NETWORK SECURITY GATEWAY SYSTEM USING ONE-WAY TELECOMMUNICATION

Номер: KR101558491B1
Принадлежит: NNSP CO., LTD.

According to an embodiment of the present invention, a security gateway can include a one-way transmission device and a one-way reception device. The one-way transmission device receives transmission data from an internal system, filters the transmission data, encodes the filtered data, and transmits the encoded data to an external device. The one-way reception device receives reception data from the external device, decodes the reception data, and transmits the decoded data to the internal system. When the data transmitted to the external device has an error, the one-way reception device receives a retransmission request from the external device receiving the data with the error previously and encodes the transmission data according to the retransmission request to transmit the encoded data to the external device. The present invention implements two-way communication by using one-way communication, thereby enhancing reliability of the security. COPYRIGHT KIPO 2016 (1100) Internal security ...
