主 题：air-space-ground integrated network terminal security trust elements sensitivity real-time judgment
摘 要：While playing an increasing role in the field of air-space integrated networks,terminal entities are exposed to more serious security risks than ordinary terminal entities on the ground,including but not limited to astronomical risks(e.g.,solar activity),link disruptions,and malicious attacks.In the integrated air-space-space network,after the terminal entity is loaded into the rocket for launch,real-time monitoring measures are implemented on the ground site for all links to the intended orbit.On top of the real-time monitoring measures,the need for a comprehensive evaluation of the air-space integration network is growing.In this paper,we further classify the security requirements and evaluation benchmarks of the terminal entities of the air-space integration network around the security evaluation requirements of the air-space integration network.On this basis,the relevant concept of trust value is introduced to assess the security status of terminal entities of air-space-sky integrated networks,and on this basis,a security assessment system of air-space-sky integrated network terminals is proposed.The exploration and development of field applications are initially realized.
