摘要
针对以巨星座为代表的现代航天技术的系统性安全问题,综合分析了空间系统面临的网络安全威胁和脆弱性。结合互联网安全大脑的成果和生成式人工智能等新技术,提出了巨星座网络安全大脑的解决方案,从数据处理、分析模型、计算架构、模拟技术等方面分析了巨星座网络安全大脑面临的技术挑战,并给出了巨星座安全大脑的概念设计与关键技术实现路径。在巨星座空间段(含链路段)、地面段、用户段分别运用安全大脑及其组件,实现数据采集与融合、安全通信与传输、供应链可信检测、智能分析与决策,并基于特有环境的数据不断优化迭代。
Aiming at the systemic security issues of modern aerospace technology represented by mega constellation,this paper comprehensively analyzes the network security threats and vulnerabilities faced by space systems,proposes a network security brain solution for mega constellation based on the achievements of the internet security brain and new technologies such as generative artificial intelligence,and gives a conceptual design of mega constellation network security brain.It analyzes the technical challenges it faces from the aspects of data processing,analysis model,computing architecture,simulation technology,etc.,and uses the security brain and its components in mega constellation space segment(contain link segment),ground segment,and user segment to achieve data collection and fusion,secure communication and transmission,supply chain trust detection,and intelligent analysis and decisionmaking,and continuously optimize and iterate based on data from unique environment.Finally,the relevant research directions of mega constellation network security brain are prospected.
