PREXT

A privacy extension for VANET

PREXT is a unified and extensible framework that simulate pseudonym change schemes (i.e. privacy schemes) in VANET. It supports seven privacy schemes of different approaches including silent period, context-based and mix-zone and can be easily extended to include more schemes. It includes adversary modules that can eavesdrop vehicle messages and track their movements. This adversary is used in measuring the gained privacy in terms of several popular metrics such as entropy, traceability and pseudonym usage statistics.

Please note that PREXT is based on the Veins framework:
