| Abstract(in English) | This paper investigates a difficulty and a threat of previous attacks on FlexRay and reports that abnormal vehicle behaviors can be induced by the most feasible attacks using a real vehicle. Recently, many studiespresented some kinds of attacks which are the threats for the real vehicles in Controller Area Network (CAN) bus and the researches on protection against such attacks become urgent issue. Although FlexRay is used for the vehicle controls of the running and driving support systems, there is few previous studies. In SCIS 2018, the DoS and spoofing attacks methods on the FlexRay protocol were proposed in details. However, this study is only theoretically proposed and a feasibility of the attacks using the real vehicles was not shown. This study investigates the difficulty and the threat of the attacks proposed in SCIS 2018 and evaluates whether the attacks, which is theoretically considered to be most feasible, is realistic or not using the real vehicles. In fact, we can induce the abnormal behaviors regarding the body control by injecting the fabricated messages effectively into the open slot inthe FlexRay communications. Furthermore, we show example countermeasures for the attacks. |
