Reputation Systems to Mitigate DoS Attack in Vehicular Network

The introduction of ICT systems into vehicles impacts on safety requirements in the automotive domain. We provide a defence mechanism based on two reputation systems: Rational and History-Based to identify insider attackers and isolate them to preserve the functionalities of the whole system. We focus on the Denial of Service attack. Finally, we experimentally evaluate our systems on a real dataset of mobility traces of taxis in Rome.
