Network isolation system based on dual one-way channel transmission technology and implementation method thereof

Abstract

The invention discloses a network isolation system based on a dual one-way channel transmission technology. The system comprises a transmitting end, a receiving end, and a transmitting channel and a feedback channel that are connected between the transmitting end and the receiving end, wherein the transmitting channel comprises network cards separately located at the transmitting end and the receiving end and a one-way transmission component connected with the two network cards, and the feedback channel comprises serial ports separately located at the transmitting end and the receiving end andthe one-way transmission component connected with the two sets of serial ports. The invention also provides a method for implementing the network isolation system based on the dual one-way channel transmission technology. The method includes the following steps: the transmitting end sends data to the receiving end through a one-way optical fiber, and the receiving end feeds the data receiving situation back to the transmitting end through a one-way serial port. Compared with an existing one-way transmission technology, the scheme of the invention is higher in reliability, faster in transmission speed and better in integration level. According to the scheme of the invention, the one-way isolation equipment can be integrated, the use cost can be reduced, and the efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and specifically relates to a network isolation system based on a dual-unidirectional channel transmission technology and an implementation method thereof proposed for a network environment requiring one-way isolation and a large amount of data interaction. Background technique [0002] In order to ensure the security of internal network data, units with network security requirements generally adopt the method of physically isolating the internal network and external network to protect the internal network. At the same time, there is also a demand for data exchange between the internal network and the external network. Most of the data exchange uses manual methods such as mobile storage devices, which has low real-time performance, low work efficiency, and consumes manpower and material resources. [0003] Existing unidirectional isolation devices mainly use two kinds of transmission co...
