A secure network data interaction system and method

Abstract

The invention discloses a safe network data interaction system, comprising: a control instruction output unit, a video encoder, and at least two subnets with mutual data isolation; each of the subnets includes an instruction receiving server and at least one client; The control instruction output unit is used to output the control instruction; the video encoder is used to encode the control instruction into image data; the image data is transmitted to the instruction receiving server of the subnet through a one-way video transmission line; The instruction receiving server in the subnet is used to receive the image data and decode the image data into the control instruction, and transmit the image data to the client corresponding to the control instruction. The present invention can realize the safe interaction of clients in multiple subnets, the whole interaction process will not change the original network security of each subnet, and avoid the interaction of each subnet due to receiving the same interactive terminal (or control command output unit) resulting in data leakage.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information transmission, and in particular to a system and method for enabling secure network data interaction. Background technique [0002] At present, complex command center interaction systems such as the government and the military need to build multiple subnets and perform data interaction on these subnets through a unified command management system. Due to security requirements, many subnets need to be isolated from the network environment. Most of the existing interactive technologies cannot interact with computers in different subnets through a unified interactive terminal, even if some can solve this interactive control problem. , but it is also realized at the expense of security by exposing these subnets and interactive terminals uniformly to the same network environment. [0003] In order to build a secure network environment, some technologies try to use unidirect...

However, if you use a serial line to transmit instructions and information, although it has the characteristics of high real-time transmission, the transmission speed of the serial line cannot meet the transmission speed requirements when processing a large amount of data.
