SpyChain: A Lightweight Blockchain for Authentication and Anonymous Authorization in IoD

Blockchain Interoperability in Unmanned Aerial Vehicles Networks: State-of-the-Art and Open Issues

“…They also addressed the issue of optimal drone positioning to enhance the overall spectral efficiency in the network. Under the same consideration, Andola et al [59] proposed a lightweight blockchain model that provides authentication and anonymity. Their work provides security preferences for a surveillance UAV.…”

PROACT: Parallel multi-miner proof of accumulated trust protocol for Internet of Drones

“…A user who requests to consume the services of a certain drone is given access to the keys of the drone to allow the user and drone to communicate in a secure manner. A system for anonymous authorization in IoD was proposed in [9]. The system hides the identities of UAVs within the exchanged message enabling only the receiver to trace back the identity of the sender.…”

“…Allowing attackers to steal users' sensitive information or forge wrong data leads to the failure of these applications. Several previous works illustrated that security-related issues in the IoD can be mitigated or resolved with the aid of powerful systems such as the blockchain (BC) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The latter, being a distributed immutable database, protects the IoD data using cryptography mechanisms such as public-key encryption and hash functions.…”
