Modeling of satellite communication systems design with physical layer security

摘要

It has practical significance to carry out research on physical layer security in satellite communication under the condition that our country has paid high attention to technology research on integrated space-terrestrial network information security. This paper addresses multiservice satellite communication using physical layer security, proposes a novel design subject to different speed and data transfer rate demand among fixed, portable, vehicle, shipborne and airborne receivers. For fixed receivers, this paper proposes a resource optimization method of satellite communication using physical layer security subject to different data transfer rate demand in many receivers. For portable, vehicle and shipborne receivers at low speed, this paper uses mean physical layer secrecy capacity to characterize the secure performance of satellite communication using physical layer security. For airborne receivers at high speed, this paper analyzes the impact of the high-speed relative motion between the satellite and the receiver on channel model, which is combined with mean physical layer secrecy capacity to characterize the secure performance of satellite communication using physical layer security.
