中文摘要:本系统主要面向涉密场景,旨在实现无线移动网络与有线局域网络之间在物理隔离条件下数据的双向传输。系统以二维码图像作为数据传输载体,移动网络采用智能手机作为数据收发节点,局域网采用计算机作为数据收发节点。系统设计有移动网络端数据库和局域网络端数据库,两个数据库表结构完全相同且不直接连接。发送端通过数据库语言筛选出两个数据库之间的差异数据,将其编码为二维码图像显示出来。接收端扫描识别二维码图像得到数据信息,完成收发两端之间数据的传输。

Desing of Confidential Network Data Transmission System Based on 2D Code
Abstract:This system is mainly for secret-related scenarios,and aims to achieve bidirectional data transmission between mobile network and LAN under the physical isolation. The system uses the 2D code image as the data transmission carrier,the mobile network uses the mobile intelligent equipment as the data transmission node,and the LAN uses the computer as the data transmission node. The system is designed with a mobile network database and a local area network database. Two database table structures are identical and not directly connected. The sending end filters the difference data between the two databases through the database language,encodes it into a 2D code image and displays it. The receiving end scans and identifies the 2D code image to obtain data information,and completes the data transmission between the receiving and sending ends.
