Method and device used for one-way transmission of data

Abstract

The invention discloses a device used for one-way transmission of data. The device comprises a first network adapter, a second network adapter, a first transmission network cable, a network device and a monitoring device, wherein the first network adapter is arranged on transmitting equipment; the second network adapter is arranged on receiving equipment; the first transmission network cable is used for connecting the first network adapter and the second network adapter; the network device is used for informing the transmitting equipment of the network connection state and / or the working state of the receiving equipment to ensure that the transmitting equipment can decide whether to stop sending data or retransmit the data; the monitoring device is used for monitoring the network connection state and / or the working state of the receiving equipment in real time, and controlling a network device to inform the transmitting equipment according to the acquired working state signals; and the first transmission network cable only transmits the data sent from the transmitting equipment to the receiving equipment. The device realizes the reliable one-way transmission of the data between different classification networks, ensures that the transmitted data cannot be repeated and lost, and meats the requirements on data transmission and only one data transmission.

Description

technical field [0001] The invention relates to network data transmission, in particular to a method and device for one-way data transmission. Background technique [0002] With the development of the Internet, most companies and government departments in my country have their own internal networks. These internal networks involve commercial secrets or government information. connect. Because these companies and government departments are also connected to external public information networks to obtain the required data and files, and there are no effective security and confidentiality protection measures between many internal networks and external public information networks, which will lead to hacker attacks and intrusions. internal network, resulting in the leakage of confidential information. [0003] In order to ensure the safe operation of secret-related networks, it is an effective security measure to implement physical isolation between secret-related networks and p...
