沉默守护者：保障卫星通信安全的至关重要性The Silent Watchers: The Critical Importance Of Securing Satellite Communications
① 卫星通信是全球基础设施的核心，但面临日益严重的网络安全威胁，如2019年斯堪的纳维亚GPS干扰事件暴露的信号脆弱性；
② 5G非地面网络（NTN）带来全新安全挑战，需采用抗量子加密和跳波束技术防范信号截获与干扰；
③ DVB-S2等传统系统通过动态密钥管理和数字水印技术加强防护，突显卫星通信系统持续安全升级的紧迫性。
① Satellite communications play a critical role in global connectivity but face growing cybersecurity threats, exemplified by incidents like the 2019 GPS disruption in Scandinavia;
② Emerging 5G non-terrestrial networks (NTN) introduce unique security challenges, requiring quantum-resistant encryption and beam-hopping techniques to prevent interception;
③ Legacy systems like DVB-S2 have evolved with enhanced encryption and real-time monitoring to address vulnerabilities, underscoring the need for continuous security innovation in satellite infrastructure.
