A safety-preserving mix zone for VANETs

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