Examining privacy in vehicular ad-hoc networks

Abstract

In this paper, we examine privacy implications within vehicular ad-hoc networks, specifically looking at DSRC. By looking at different possible applications for VANETs, we get an idea for the consequences of a privacy breach within VANETs. We examined the DSRC protocol stack for potential privacy violations, and found privacy violating messages within those standards. We also address general attacks on privacy such as location tracking and correlating pseudonyms. Finally, we examine proposed schemes for preserving privacy within VANETs.
