基于网闸的异构数据库安全同步系统

Heterogeneous Database Security Synchronization System Based on GAP

在工业控制领域,因为边界防护安全的要求,网闸普遍应用于生产控制区域与管理信息区域之间的物理隔离中。异构数据库之间数据同步是目前工业生产中常见的一种应用场景。针对存在物理隔离网闸的应用环境,提出在跨安全区的情况下,屏蔽安全隔离设备以及两侧数据库的异构差异,实现数据库数据同步方法。通过给出数据变化探知、数据加密压缩、编码融合等实现细节,阐述网闸环境下异构数据库同步原理。最后通过实验,验证提出的方法能够实现异构数据库数据安全传输的目标。

In the field of industrial control, because of the security requirements of border protection, the GAP technology is widely used in the physical isolation between production control area and management information area. Data synchronization between heterogeneous databases is a common application scenario in industrial production. In view of the application environment with physical isolation GAP, this paper puts forward a data synchronization method for databases by shielding the security isolation devices and the heterogeneous differences between databases on both sides in the case of cross security zones. This paper describes the synchronization principle of heterogeneous databases in the GAP environment by providing details of data change detection, data encryption and compression, and coding fusion. Finally, the experiment verifies that the proposed method can achieve the goal of data security transmission in heterogeneous databases.
