Towards secure and resilient unmanned aerial vehicles swarm network based on blockchain

IET Blockchain, Volume 4, Issue S1, Page 483-493, December 2024.
Abstract Blockchain, as an emerging technology, has found diverse applications in solving trust issues in multi‐party cooperation. The field of Unmanned Aerial Vehicle (UAV) swarm networks is no exception, as UAVs are susceptible to attacks from malicious counterparts due to limited computing and storage resources. In this paper, the authors present an
