| Outline of Final Research Achievements |
The requirement of security and privacy in ITS networks is different from the general Internet. Specifically, each vehicle periodically broadcasts vehicle ID, position and speed information as it moves, and surrounding vehicles receive the information to improve safety such as collision avoidance. Using this characteristic, we developed a method for detecting vehicle misbehavior and detecting illegal data, and showed its effectiveness by simulation. In our research, it was shown that the detection rate of malicious data is improved by increasing the threshold value by taking measures against vehicle information disguise. We also developed a method for tracking malicious information when a malicious vehicle is found, even if the vehicle moves.
