基于OGC规范的空间信息网格安全体系研究

Research on Security Framework of OGC-based Spatial Information Grid

网格技术在空间资源共享上起到了很大的作用,海量遥感数据、复杂的测量数据、专业的地学软件、科学的计算模型等数据和计算资源通过服务化技术,在网格环境能够提供一体化、按需服务。为了保证资源所有者的控制权和资源的私有性以及用户的隐私,需要设计一个完整的安全体系来从资源层、传输层、服务层、应用层等各个级别保证安全,同时要尊重网格节点的自治性和网格服务的整体性。本研究能够为跨区域、跨组织的数据和计算资源网格化共享的安全方案提供借鉴作用。

Grid technology has been used widely in spatial resource sharing.Many kinds of resources（such as large amount of remote sensing images,complex observation data and professional geographical software）can be integrally accessed on Internet on demand through grid environment.In order to protect the owner’s right,resource’s security and user’s privacy,the security framework is needed.The framework should be comprehensive enough to cover the resource layer,service layer,transport layer,application layer etc.Meanwhile,the framework should keep each node of the grid themselves.This research could give advice to those applications which are cross regions,cross organizations and share the resource through services.
