Traceability and safety tradeoffs in modern vehicles
| Resumo: | In this dissertation, the efficiency of privacy protecting mechanisms in short-range vehicular communications, namely Pseudonym Change Strategies, is investigated. To evaluate these strategies, a set of simulation tools is used, that allow for the assessment of several metrics, such as the privacy level obtained and the real pseudonym consumption, resulting from the use of a representative set of pseudonym change strategies. Most importantly, hybrid strategies were considered, which combine schemes that were previously analysed separately. The results show that combining mix-zones with another scheme provides better privacy in most cases. Lastly, we showcase and analyse the problems found in the process of trying to make the simulated scenarios more realistic, which easily comes into conflict with tool limitations and/or subtle and hard to anticipate interactions between different components. |
