Unmanned Aerial Vehicles (UAVs) enabled Internet of Things (IoT) systems are evolving as effective solutions to critical application including surveillance, agriculture, healthcare, supply chain managements, smart cities, rescue operations and more. Remotely controllable sensors mounted on UAVs are solving issues related to reaching out physically inaccessible areas or remote locations being monitored or controlled by IoT applications. Though fusion of UAVs and IoT proves disruptive, it needs to address increased security issues. Identity management, authentication, UAV hijacking, secured and trustworthy data sharing in intra‐UAV communications, UAV signal jamming are few in the series. Blockchain being a decentralized technology and a distributed ledger offers solutions to some of these issues. Blockchain assures secure intra‐UAV communications through encryption and hashing. In case of UAV signal jamming, UAV can use blockchain to prepare the flying schedule. Consensus mechanism of blockchain can detect the internal attacks or malicious insider UAV. Blockchain technology provides transparency and trust in trust‐less environments involving third parties or multiple parties collaborating to provide UAV based IoT applications and services. Blockchain promises immutability of transactions thereby providing opportunity to thwart out many cyber‐physical systems attacks on UAV based IoT systems. In this work we explore the blockchain‐based solutions for various security issues in UAV‐enabled IoT.
