| Outline of Final Research Achievements |
In this study, we focused on the analog signals that are input and output to the sensor, and evaluated the attack potential and examined the countermeasure technology regarding the security in the acquisition process of the sensor device that acquires the external information by the autonomous control system. . We constructed an attack reproduction environment using an actual sensor to evaluate the attack potential, and revealed that the attack range expanded when the attacker could acquire the measurement timing of the sensor through electromagnetic waves in the process. In addition, as a countermeasure technology, it was shown that even if an attacker acquires an analog signal externally, it may be difficult to reproduce it due to nonlinearity in the process of converting digital signal modulation into an analog signal.
