| Outline of Final Research Achievements |
This research clarified the threat of cyber-physical cooperative attacks on embedded systems and developed effective countermeasure techniques for this kind of attack. We first survey and classify cyber-physical cooperative attacks that can pose a threat to embedded systems equipped with general cyber attack countermeasures in a systematic manner. In particular, we focused on buffer overflow (BOF) attack and fault injection attack as a cyber attack and a physical attack, respectively. We have developed an efficient software countermeasure method against their cooperative attacks. In addition, we built an evaluation / analysis system that can reproduce typical cyber-physical cooperative attacks and demonstrated the security and efficiency of the developed countermeasure method.
