A probably secure biometric‐based authentication and key agreement scheme for Internet of Drones

Abstract

The Internet of Drones (IoD) is one of the world's most recent and innovative technology. Drones are most prominent IoT (Internet of Things) gadgets and their applications span from commercial to domestic. The sensitive data stored in drones has increased the demand for the security of communication in the IoD. As a result, numerous authentication and key agreement techniques have been developed to proffers secure communication among the entities of the IoD network. However, after scrutinizing the security of these protocols, many IoD protocols were observed to be susceptible to different cryptographic attacks. This has enhanced the necessity for an improved and efficient authentication scheme in IoD. In this article, we first investigate Zhang et al.'s approach and demonstrate that although it offers security verification, it has certain design problems. It is, furthermore, shown to be vulnerable to privileged insider, offline password guessing, and stolen smart device attacks. Second, we propose a novel biometric‐based scheme that includes countermeasures to protect against these flaws. The security of the mechanism is examined under real or random oracle model, informal security analysis and scyther simulation for numerous cryptographic assaults. Also, the performance analysis substantiates the competency of the proposed scheme corresponding to computation and communication cost with existing schemes.
