“星链”安全设计理念初探

Preliminary Exploration on the Security Design Concept of Starlink

美国SpaceX公司的“星链”是目前全球商业化应用最广泛的卫星互联网系统。出于保护商业秘密的原因,SpaceX极少向外界透露有关“星链”系统的安全设计信息。根据SpaceX官方网站发布的少量信息,对“星链”终端和系统的安全设计理念进行了介绍,对应用中面临的挑战和关键技术进行了探讨,并对国内卫星互联网安全设计提出了建议。

SpaceX’s Starlink is the most widely commercialized satellite Internet system in the world.For reasons of protecting trade secrecy,SpaceX rarely discloses information about the safety design of the Starlink system to the public.Based on the small amount of information released on the official website of SpaceX,this paper introduces the security design concept of Starlink terminal and system,discusses the challenges and key technologies in its application,and makes suggestions for the security design of China’s satellite Internet.
