Abstract:

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.

Key words: GAP, heterogeneous data, data synchronization, security transmission
