Quantum-Secured Space-Air-Ground Integrated Networks: Concept, Framework, and Case Study. (arXiv:2204.08673v1 [cs.CR])

In the upcoming 6G era, existing terrestrial networks have evolved toward
space-air-ground integrated networks (SAGIN), providing ultra-high data rates,
seamless network coverage, and ubiquitous intelligence for communications of
applications and services. However, conventional communications in SAGIN still
face data confidentiality issues. Fortunately, the concept of Quantum Key
Distribution (QKD) over SAGIN is able to provide information-theoretic security
for secure communications in SAGIN with quantum cryptography. Therefore, in
this paper, we propose the quantum-secured SAGIN which is feasible to achieve
proven …
