Study of threat for automotive embedded system by Trojan virus

In recent years, vulnerability of information security of automotive embedded systems has been indicated. Especially, Trojan, which falsifies programs of Electronic Control Unit (ECU), has serious threat for the safety of a car. Therefore, measures against the Trojan are particularly important to secure automotive embedded systems. However, few studies for the Trojan on automotive embedded systems have been reported. This study elucidates the tendency of the Trojan for the ECU software. Experiments show that it is difficult to detect Trojan for ECU software.
