In this part of the thesis, a novel approach for obfuscating pseudonym changes based on dynamic cryptographic Mix Zones is presented. While geographical cells are used to establish a secret group key among all members, the group is maintained even when travelling along the road. Using the group key, a vehicle is able to send authenticated messages, though its anonymity is preserved.
