Abstract:A shared research experiment was performed to prove that tracking of Wi-Fi enabled clients is possible. Then individually a solution for the problem was developed, verified and tested. The goal was to minimally change the protocol to prevent tracking but to keep interoperability with older devices. In the shared experiment students’ data was collected and they tracked their household occupancy. Using the collected Wi-Fi data a schedule was generated and compared to the actual schedule. Unfortunately this was not possible because the students were all on the same network which made it impossible to separate households and their devices from their neighbours. The individual part started by determining which parts of the protocol allow tracking of the clients. It was then implemented in Proverif to verify that the data leaked. It was then altered to not leak any of the data whilst staying compatible with older devices. It was then implemented on devices to verify the compatibility of the new protocol with the old one. Determining the problem, proving and creating a solution in Proverif were all successful. The last part could not be successfully implemented. Thus, the interoperability could not be verified though only small changes were made.
