Sybil Attack Detection with Reduced Bandwidth Overhead in Urban Vehicular Networks

Abstract

Over the past two decades, vehicular networks have been emerging as a cornerstone of the nextgeneration Intelligent Transportation Systems (ITSs), contributing to safer and more efficient roads by providing timely information to drivers and concerned authorities. In vehicular networks, moving vehicles are enabled to communicate with each other via inter-vehicle communications as well as with road-side units (RSUs) in vicinity via roadside-to-vehicle communications. In urban vehicular networks where the privacy, especially the location privacy of vehicles should be guaranteed, vehicles need to be verified in an anonymous manner. In urban vehicular networks, where privacy, especially the location privacy of anonymous vehicles is highly concerned, anonymous verification of vehicles is indispensable.
