RETRACTED ARTICLE: Location Privacy with Dynamic Pseudonym-Based Multiple Mix-Zones Generation over Road Networks

According to the recent studies, application related with safety associated with road networks must need verification of entities and messages. However, security of road network users like vehicles and drivers needs to be dealt with. Unique identity like pen names and certificates might get useful to ensure security. Pseudonym names and the special certificates are being considered as the basic building blocks to ensure security requirements for road networks. Nevertheless, apart from the seen advantages, road network communication might also generate certain privacy issues by giving opportunity to invader to track vehicles. One and for most basic technique is to solve this issue by means of using pen names by the vehicles and alter them time to time. Since executing the procedure of changing pen names has to increase overhead. By looking at such type of limitations, our given technique will produce top privacy level for the road network users by using dynamic pseudonyms based multiple mix zones scenario. This pseudonym based procedure will base upon vehicle’s acceleration, heading and displacement to execute dynamic pseudonym alteration. We have performed simulation by applying SUMO simulator. After having a detailed comparison with the current pseudonym change techniques, it has been verified that our given technique has shown enhanced performance in terms of acquiring top level privacy rate having few numbers of pseudonyms alteration; broad level of simulations and analysis has been elaborated the efficiency of the given technique.
