@@@@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 prospected.
