Problems solved by technology
[0003] In the one-way physical isolation system, the information data can only be isolated and transmitted in one direction from the external network to the internal network. The information data based on the one-way isolation technology can only be isolated and transmitted from the sending end to the receiving end, and cannot be reversed. To transfer receipt data, the integrity of information data transmission is not guaranteed

The present application provides a method and device for data transmission with one-way physical isolation, which specifically includes: when the first network device needs to send original data to the third network device, sending the original data to the optical splitting device; The spectroscopic device receives the original data, splits the original data according to a preset ratio, obtains corresponding first data and second data, sends the second data to the second network device, and transmits the first data to the second network device. A data is sent to the third network device. The present application can verify the second data based on the communication between the first network device and the second network device, and confirm the integrity of the data, which is beneficial to improve transmission efficiency, reduce resource consumption, and the like.
Description
technical field [0001] The present application relates to the field of communications technologies, and in particular, to a method, apparatus, device and storage medium for data transmission with unidirectional physical isolation. Background technique [0002] The existing one-way physical isolation system realizes one-way data transmission through effective control of the physical layer, and completely solidifies the data transmission mode and data flow direction, thereby ensuring that the data is transmitted in a controlled manner in the forward direction and prohibited from passing in the reverse direction. As a dedicated high-protection-level security device, the system is deployed between high-density networks and low-density networks to strictly limit data transmission flow and data content. Therefore, when data is released to the outside, only controlled data output is allowed to prevent malicious attacks from external networks; when data is received inward, only cont...
