摘要
随着卫星互联网等大规模星座空间网络互联发展,太空系统天地一张网的网络属性愈加凸显,太空网络安全威胁的现实可能性与日俱增且后果严重。基于太空系统体系架构和网络连接特性,分析了太空系统空间段、链路段、地面段的网络物理属性和随轨道运行通断的异构网络互联属性;统计分析了自1957年至今全球太空网络安全威胁的典型开源案例,研究了国际上地对天网络入侵、天对天网络对抗等太空网络安全威胁技术突破和能力发展;针对不同太空网络安全威胁能力等级,对威胁渠道及可能的实施途径及代价进行了深度剖析与发展趋势研判,并给出了基本观点。
With the development of space network interconnection of large-scale constellations such as satellite Internet,the characteristic of the integrated network of space and earth is growing day by day with serious consequences.Based on the architecture and network connectivity characteristics of the space system,the physical properties of the space segment,chain segment,and ground segment networks of the space system,as well as the heterogeneous network interconnection properties of the‘on/off’orbital operation are analyzed.A statistical analysis of typical open source cases of global space network security threats from 1957 to present is conducted,and the technological break-throughs and capability development of space network security threats such as ground to space pene-tration and space to space penetration by major international space organizations are analyzed.Then,a deep analysis and assessment of attack channels and possible implementation approaches are con-ducted for different levels of space network security threat capabilities.Finally,basic viewpoints are provided.
