In vehicular ad hoc networks, vehicles may be tracked due to the frequent sending of beacons containing telemetic data. Even changing the vehicle’s pseudonym cannot prevent attackers from linking beacons. Previously published solutions require vehicles to stop sending beacons when changing their pseudonyms, resulting in the loss of safety. We propose a novel concept based on the approach of mix zones, providing a compromise between privacy and safety. Therefore we introduce a communication proxy inside the mix zones. Simulations show that this approach is technically feasible, even with common hardware.
