摘要
物理层安全技术为通信信息安全研究开辟了新的途径。论述了卫星通信物理层安全技术应用的可行性,分析了现有物理层安全技术及其应用于卫星通信的潜在问题,提出了卫星通信物理层安全可研究方向,及基于单星平台、星座平台、天基平台通信系统条件下的关键技术,展望了卫星通信物理层安全技术的发展前景。
The technology of physical layer security（PLS） has provided a new way for information protection. This paper discusses the applications of PLS in satellite communications（SC）. First, the foundation of PLS is in- troduced, and several popular PLS methods used in terrestrial wireless communication are reviewed. Second, the possibilities of applying those methods on SC are discussed with different platforms, including single-satellite, constellation and space platform. Finally, the prospect of PLS in SC is omsDected.
