摘要
基于GML编码的数据在构建地理信息发布系统的三层体系结构中,发挥着重要的作用,但是GML数据自身的机密性难以在地理信息发布的过程中得以保证。本文分析了这种地理信息发布过程中安全传输机制的不足,提出了GML数据加密、解密的过程,最后给出了一个应用实例加以说明。
The coding data based GML plays an important role in building the three-layered system construction of geography information publishing.However,it is the difficulty for us to ensure the confidentiality of GML data in the course of geography information publishing.This article analyzed some information hidden dangers in the transmission of GML in geography information publishing,and gave us the course of GML encryption and decipher.At last,it explained us an application in GML encryption.
