卫星互联网发展趋势及网络安全治理研究综述OA

Satellite internet technology is evolving from a communications technology into a critical infrastructure and a core technological force in global strategic competition.However,it faces security threats across the entire chain—from satellites and ground systems to user terminals and cloud platforms.This underscores the urgent need to establish a more comprehensive cybersecurity governance framework from the per-spective of national security.This paper systematically reviews major development trends in satellite internet,including the dominance of low Earth orbit(LEO)constellations,the integration of 6G and artificial intelligence(AI),and direct-to-device(D2D)satellite communica-tions.It further analyzes main risks such as multidimensional security threats,impacts on cyber sovereignty,cross-border data transmission risks,and the lag of international regulatory frameworks.Through a comparative study of governance practices in the United States,the Euro-pean Union,China,Russia,the United Kingdom,India,and Japan,the paper summarizes the major experiences and approaches in satel-lite internet cybersecurity governance.In response to the shared challenges of global satellite internet development,the paper proposes several policy recommendations,including establishing a multilateral and coordinated international regulatory framework,strengthening full-chain se-curity and supply chain resilience,and promoting inclusive global satellite internet infrastructure development.
