地理空间信息网格安全问题解析及安全体系结构研究

计算机网络是地理空间信息网格的载体,二者之间有着密切的联系。其关联性主要表现在互连互通、基于协议、交互接口和虚拟组织几个方面。因此,计算机网络遇到的安全威胁,地理空间信息网格也同样会遇到。此外,地理空间信息网格还要面对自身特征带来的诸如攻击核心设施,导致整体瘫痪或破坏局部计算等各种安全威胁。针对这些问题,本文基于用户、通信网络、应用程序、网格资源四个环节,研究设计了地理空间信息网格安全体系结构,并论述了各模块功能和相互之间的关系,以及整体协同运行程序。

On Security of the Geospatial Information Grid

The computer network is the carrier of Geospatial Information Grid. There is a close relationship between computer network and Geospatial Information Grid. The relationship mainly represents in interconnection, protocol-based, mutual interface, and virtual organization, etc. Therefore, both of computer network and Geospatial Information Grid encounter the security threat. In addition, the Geospatial Information Grid has to face the other security threats caused by the own characteristics, such as attack core installation, which could result in whole collapse, or destruction partial computation. Directing against these questions, based on the user, the correspondence network, application program and grid resources, this article researched and designed the security structure of Geospatial Information Grid, and elaborated various modules function and mutually relations, as well as whole coordinated programming.
