However, due to the open-access communication environment, IoD also raises security and privacy concerns, including authentication threat as well as the leakage of identity, location, and flying routes. In order to address the security and privacy concerns in IoD, this paper proposes an efficient privacypreserving authentication framework. By utilizing the lightweight online/offline signature design, our framework assures the authentication efficiency when deploying on resource-constrained small-scale UAVs. Considering the high mobility of UAVs, a predictive authentication approach is investigated with mobile edge computing (MEC) in our framework to further reduce the authentication cost for potential authentication activities. Meanwhile, by designing a buffer pseudonym and public key update strategy, our framework enables the protection of privacy in terms of UAVs' identity, location, and flying routes. Thorough analysis is carried out to demonstrate the fulfillment and feasibility of our framework in terms of security, privacy, and efficiency.

VANET (Vehicular Ad-Hoc Network) is considered as an intelligent transport system where in the vehicles can able to communicate with each other and also with the road side infrastructure. Since the message exchange between two vehicles are ad-hoc in nature and the driver behavior and high mobility of the vehicle, there is a chance of privacy and security problems and also the authentication is an another issue for any secured interactions due to the VANET has a unsecured and untrusted nature. The paper reviews various existing authentication protocols used for efficient privacy preserving authentication in the VANET.
