Block Chain-based Access Control with Optimal Key Generation in Internet of Drones

Recently, there is a growing interest in the research of Internet of Drones (IoD) owing to its applicability in numerous fields, including civilian and military. The information gathered by the drones is transmitted over the internet, which makes them vulnerable to privacy and security threats. Hence, efficient methods of providing security to IoD are necessary to provide authenticity, integrity and confidentiality of data. These issues can be effectively handled by using blockchain, which is an immutable ledger-based technology. In this paper, a block chain-based access control system is developed based on an optimal key generation. The method is implemented using various phases, such as Pre-deployment, registration and authentication, Drone to drone (D2D) access control phase, Drone to server access control phase and Emergency access control phase. A coot algorithm based key generation is utilized in the D2D access control phase and Drone to server access control phase. Further, the performance of the COOT Keygeneration-based Access control is evaluated using metrics, such as delay, packet loss rate and throughput and the value obtained are 0.0725 sec, 0.883% and 73.547 bps respectively.
