Key management technology analysis based on UAV cluster communication security

With the wide application of Unmanned Aerial Vehicle (UAV) cluster in military and civil applications, the security of network communication of UAV cluster has been paid more attention and become a key research field. Key management technology is the critical factor in ensuring the security of the cluster network. This paper analyzes the security of UAV cluster communication based on key management technology. Firstly, this paper classifies UAV according to its use and designs the UAV cluster network communication model. Then, this paper discusses the security threat of UAV cluster network communication. Finally, this paper refined the key management process of UAV cluster, designed the logical architecture of UAV cluster key management, and analyzed the key management technology, to facilitate the subsequent design of specific UAV cluster key management scheme and ensure its communications security.
