Abstract:

As a typical application of wireless communications,the air-space-ground communications networks are facing serious wireless communications security issues due to its inherent broadcast nature and wide coverage.Especially in the field of military satellite communications,the requirement of secure communications security is even more crucial.How to realize the security of communications is a problem must be faced.A model for physical layer security communication in air-space-ground communication network was proposed which was a cooperative layer-direct connect mixed-to-ground physical layer secure communication model.Based on this model,the security of the system was further improved by studying the relay selection problem and the power distribution problem of satellite and relay,and an overall scheme to enhance the confidentiality of the communication network was also proposed.

Key words: air-space-ground communication network, physical layer security, relay selection, power allocation
