Resumo


For some time the vihicles adopted distributed electronic systems as a way to bring more comfort, active ande passive safety to the occupants. With the increase of technological demond and innovations in connectivity, vehicles became attractive to hackers. Regardless of goals of hacking, the future of automobiles goes through a wide range of related work evaluating the impacts of malicious people that take control of the vehicle”s systems. In this article we evaluate the vulnerabilities of a vehicular data bus, CAN and CAN-FD. It is possible for an intruder to interfere with instrument panel display systems by sending forged messages to the driver and even compromise sustems related to safety such as steering and brakes. Among the various types of possible attacks on the CAN bus, the D.o.S. (Denial of service) lacks of a deeper discussion in the literature. This article proposes a mechanism to protect the bus from this type of attack. A filter is designed to avoid that the bus be overloaded with false requests, providing access to authentic message exchanging
