摘要
从网络信息安全的一般性问题入手,研究了以多层网络服务结构为核心、网络安全传输算法为基础、授权管理、监控审计和身份认证为辅助,同时兼顾性能、并具扩展性的分布式空间信息网络服务安全架构;并以多种比例尺地理空间矢量数据、高分辨率卫星影像数据和各种专题数据为数据源,建立了高质量、高稳定性和高可靠性的空间信息网络服务系统;解决了地理空间数据共享与网络服务安全的矛盾,为应用部门提供地理空间信息查询和分析服务,具有重要的使用价值和现实意义。
With the universality of network information safety as start point, the distributed spatial information network service security architecture were discussed by taking the multi-layered network service structure as the core and authorization management, monitoring audit, authentication as the supplementary. And both performance and extension were taken into account. With the multi-scale geography space vector data and the high resolution satellite phantom as the data pool, a spatial information network service system with high grade, high stability and redundant reliability was built, which solved the contradiction between geo-spatial data sharing and spatial data safety, and provided the geography spatial information inquiry and the analysis service for the application department.
