SlotSwap: Strong and Affordable Location Privacy in Intelligent Transportation Systems
Public acceptance, and thus the economic success of an Intelligent Transportation System (ITS), is highly dependent on the quality of deployed privacy mechanisms. In general, neither users nor operators should be able to track a given individual. One approach to facilitate this is the usage of pseudonym pools, which allow vehicles to autonomously switch between different identities. The authors extend this scheme with that of a time-slotted pseudonym pool of static size, reducing the storage and computation needs of the envisioned ITS while further improving users' privacy.
