ABSTRACT
We investigate how to obtain a balance between privacy and audit requirements in vehicular networks. Challenging the current trend of relying on asymmetric primitives within VANETs, our investigation is a feasibility study of the use of symmetric primitives, resulting in some efficiency improvements of potential value. More specifically, we develop a realistic trust model, and an architecture that supports our solution. In order to ascertain that most users will not find it meaningful to disconnect or disable transponders, we design our solution with several types of user incentives as part of the structure. Examples of resulting features include anonymous toll collection; improved emergency response; and personalized and route-dependent traffic information.

Examining privacy in vehicular ad-hoc networks
DIVANet '12: Proceedings of the second ACM international symposium on Design and analysis of intelligent vehicular networks and applicationsIn 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 ...
