SYSTEM AND METHOD FOR DETECTING AND EVICTING MALICIOUS VEHICLES IN A VEHICLE COMMUNICATIONS NETWORK

摘要

In a vehicle communication network, some vehicles may be used by attackers to send false information to other vehicles which may jeopardize the safety of other vehicles. Vehicles should be able to detect malicious communications activities and to mitigate the impact of malicious vehicles by evicting (eliminating) suspected malicious vehicles from the system. Evicting a vehicle is to ignore the messages sent from the vehicle for a specified time period. Voting and sacrifice principles are combined using a mathematical model based on the “Mafia Game”. The Mafia Game model focuses on the relative size of the group of attackers within a neighborhood necessary to dominate the entire network in the neighborhood (i.e., to eventually evict all the innocent vehicles).

主权项

1. A method for vehicles to detect and evict malicious vehicles in a vehicle-to-vehicle communications network using the Mafia Game theory, comprising:
malicious mafia vehicles that have been detected to behave significantly differently from the behaviors designed by the vehicle manufacturers, innocent vehicles that behave as designed by the vehicle manufacturers, vigilante vehicles vehicles that are deemed or verified by a detective vehicle as an innocent vehicle which is a vigilante vehicle, and detective vehicles that are innocent vehicles that have the ability to detect whether another vehicle is an innocent vehicle or a malicious vehicle, or a vigilant vehicle, where resident vehicles are vehicles of all categories in a region.
