Research on Security Mechanism of Sharing System Based on Geographic Information Service

Abstract

In order to enhance the security of the spatial data in the information sharing system based on the WFS services, this paper analyzes the hidden danger of the spatial data in the calling WFS service process. On this basis, the paper built a WFS security service module based on the XML key management, the XML digital signatures, the XML digital encryption security specifications, and geospatial extensible access control markup languages. The module is located between the client and geographic information server, before providing the WFS geographic information services, it can quickly and effectively distinguish the user’s identity, operating authority, and has the ability to encrypt transmitted spatial information and accomplish integrity, nonrepudiation verification.
