A Lightweight Seamless Authentication Scheme for Edge-Assisted IoV networks

초록

Internet of vehicles (IoV) is an expanded concept of vehicular ad-hoc networks (VANET), and it is more scalable and can be combined with the latest mobile communication technology such as 5G and 6G. The IoV environment aims to realize autonomous driving through communication such as vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), and vehicle-to-person (V2P). Among them, V2I interaction is the most basic communication. In IoV environments, vehicles have mobility, and it is very frequent to authenticate with the same RSU or another RSU after authenticating with a RSU in its first region. If the authentication process is repeated in re-authentication situations, it can put a burden on the vehicle and RSU and have negatively the performance of the network. In this paper, we proposed authentication protocols considering three situations: Initial authentication, re-authentication, and handover authentication. We demonstrate that our scheme has resistance to various attack scenarios, and compared the performance of the proposed scheme with existing schemes. © 2023 IEEE.
