2014. PADAVAN: Privacy-Aware Data Accumulation for Vehicular Ad-hoc Networks. Wireless and Mobile Computing, Networking and Communications (WiMob), 2014 IEEE 10th International Conference on. :487-493.
In this paper we introduce PADAVAN, a novel anonymous data collection scheme for Vehicular Ad Hoc Networks (VANETs). PADAVAN allows users to submit data anonymously to a data consumer while preventing adversaries from submitting large amounts of bogus data. PADAVAN is comprised of an n-times anonymous authentication scheme, mix cascades and various principles to protect the privacy of the submitted data itself. Furthermore, we evaluate the effectiveness of limiting an adversary to a fixed amount of messages.
