Vehicular Ad hoc Network (VANET) has gone through a rich amount of research and currently is making its way towardsthe deployment. However, surprisingly it evolved to rather more applications and services-rich breed referred to as VANET-basedclouds due to the advancements in the automobile and communication technologies. Security and privacy have always been thechallenges for the think tanks to deploy this technology on mass scale. It is even worse that some security issues areorthogonally related to each other such as privacy, revocation and route tracing. In this paper, we aim at a specificVANET-based clouds framework proposed by Hussain et al. namely VANET using Clouds (VuC) where VANET and cloud infrastructure cooperate with each other in order to provide VANET users (more precisely subscribers) with services. We specifically target the aforementioned conflicted privacy, route tracing, and revocation problem in VANET-based clouds environment. We propose a multiple pseudonymous approach for privacy reasons and leverage the beacons stored in the cloud infrastructure for both route tracing and revocation. In the proposed scheme, revocation authorities after colluding, can trace the path taken by the target node for a specified timespan and can also revoke the identity if needed. Our proposed scheme is secure, conditional privacy preserved, and is computationally less expensive than the previously proposed schemes.
Abstract
Vehicular Ad hoc Network (VANET) has gone through a rich amount of research and currently is making its way towardsthe deployment. However, surprisingly it evolved to rather more applications and services-rich breed referred to as VANET-basedclouds due to the advancements in the automobile and communication technologies. Security and privacy have always been thechallenges for the think tanks to deploy this technology on mass scale. It is even worse that some security issues areorthogonally related to each other such as privacy, revocation and route tracing. In this paper, we aim at a specificVANET-based clouds framework proposed by Hussain et al. namely VANET using Clouds (VuC) where VANET and cloud infrastructure cooperate with each other in order to provide VANET users (more precisely subscribers) with services. We specifically target the aforementioned conflicted privacy, route tracing, and revocation problem in VANET-based clouds environment. We propose a multiple pseudonymous approach for privacy reasons and leverage the beacons stored in the cloud infrastructure for both route tracing and revocation.
