Security and privacy of UAV data using blockchain technology

The utility of virtual circuit (VC) based devices UAVs, Drones, and similar other IoT based devices have gained immense momentum in the present day and age. These devices are predominantly used for aerial surveying in sensitive and remote areas. It is alarming that issues pertaining to stalking and information control have increased with the growth of technology. This paper presents a Blockchain Technology (BCT) based solution to improve the security and privacy of VC based device data. The proposed design is evaluated by implementing an IoT based application in a virtual vehicle monitoring system. The technical information about the instructions to the vehicle (devices), authentication, integrity, and vehicle reactions are stored in a cloud platform wherein Pentatope based Elliptic curve cryptography and SHA are used to ensure privacy in data storage. The data is later stored in an Ethereum based public blockchain to enable seamless BCT transactions. This system uses the Ganache platform for BCT that ensures data protection and privacy. Furthermore, metamask wallet for Ethbalance is required to perform transactions over BCT. The proposed methodology thus helps to protect data from stalkers, plaintext attacks as well as ciphertext attacks. The results, when compared with the state-of-theart, justify the efficiency and security aspects of the proposed approach.
