A New Efficient PUF-Based Mutual Authentication Scheme for Drones

This paper proposes a new lightweight mutual authentication scheme for drones that is based on a Physical Unclonable Function (PUF) which uses type-III pairing friendly elliptic curves, and cryptographic accumulators. The use of a PUF in this scheme helps to avoid the risk of drone cloning. Additionally, the use of elliptic curves allows for a lightweight mutual authentication scheme that satisfies many security requirements, such as secrecy and forward secrecy. Furthermore, this paper allows direct mutual authentication between drones. The cryptographic accumulator accumulates the entire drone identity database into a single element, which reduces the amount of data that needs to be stored on a drone. Moreover, the proposed scheme is, in the worst case, equivalent to the most recent PUF-based mutual authentication schemes for drones in terms of communication data. Moreover, this paper give an implementation of the proposed scheme.
