摘要：
在用户需求持续增长、成本降低以及技术进步的推动下，低地球轨道（Low Earth Orbit, LEO）卫星正处于快速发展阶段。由于目前关于LEO卫星通信系统（Satellite Communication Systems, SCSs）安全性与可靠性问题的文献较为匮乏，本文旨在填补这一知识空白。具体而言，本文批判性地评估了LEO SCSs的固有特性，并详细阐述了其安全性与可靠性要求。在此基础上，本文进一步探讨了其存在的脆弱性，包括可能遭受的安全攻击以及可靠性风险，随后概述了从中得到的经验教训。接着，本文讨论了相应的安全性与可靠性增强方案，揭示了一系列需要权衡的因素，并总结了从中获得的启示。此外，本文阐明了提升LEO SCSs安全性与可靠性的若干有前景的未来研究方向，例如一体化感知与通信、计算机视觉辅助通信，以及巨型星座和商业化带来的挑战。最后，本文总结了推导得出的经验教训，并在设计准则中明确了核心要点。
英文摘要：
Low Earth Orbit (LEO) satellites undergo a period of rapid development driven by ever-increasing user demands, reduced costs, and technological progress. Since there is a paucity of literature on the security and reliability issues of LEO Satellite Communication Systems (SCSs), we aim to fill this knowledge gap. Specifically, we critically appraise the inherent characteristics of LEO SCSs and elaborate on their security and reliability requirements. In light of this, we further discuss their vulnerabilities, including potential security attacks launched against them and reliability risks, followed by outlining the associated lessons learned. Subsequently, we discuss the corresponding security and reliability enhancement solutions, unveil a range of trade-offs, and summarize the lessons gleaned. Furthermore, we shed light on several promising future research directions for enhancing the security and reliability of LEO SCSs, such as integrated sensing and communication, computer vision aided communications, as well as challenges brought about by mega-constellation and commercialization. Finally, we summarize the lessons inferred and crystallize the take-away messages in our design guidelines.
