Robust and anonymous handover authentication scheme without key escrow problem in vehicular sensor networks

摘要

Vehicular ad hoc Networks (VANETs) encompass the Internet of Vehicles, Vehicular Sensor Networks (VSNs), and electronic vehicles and tend to be an essential part of the world. In this network, communications are done through an open channel and are inevitably susceptible to a range of security issues. Their high mobility also adds to this concern. Roaming services are essential for global VANETs and mobility-based networks, which require a robust authentication mechanism to be maintained. Therefore, an effective and secure authentication and session key agreement mechanism in VANET is a challenge yet to be tackled. Recently, different three-party schemes were proposed to use in the handover authentication process, though they have their deficits. The present study showed that the three related schemes (Zhou et al., Patonico et al., and Eftekhari et al.) have security flaws such as insecurity against impersonation attack, key compromise impersonation attack, and man-in-the-middle attack. Also, a secure and robust handover authentication scheme is proposed for roaming service in VSNs, which stamps out the existing schemes' security problems. It considers the intra-network and inter-network roaming authentication models. Our proposed scheme, free from key escrow problems, is highly anonymous and provides forward/backward secrecy. Widely accepted random oracle model, AVISPA tool, and BAN logic used for security analysis. Our scheme outperforms the others in security metrics and improves communication overhead by up to 75%. Also, the simulation results show that our scheme is energy-efficient and imposes a lower end-to-end delay to the network.
