Physical Layer Security Schemes in Space-Integrated-Ground Information Network

Abstract

Firstly, the current mainstream technologies of physical layer security were summarized and the relevant technical indicators were introduced; Then, the research on physical layer security in three typical scenarios of the space-integrated-ground information network was summarized; Finally, problems need to be solved for the physical layer security of the three typical scenarios were proposed, and feasible schemes were discussed.
