| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Nowadays, as the number of IoT computers increases, the risks of malicious replacement and spoofing (and so on) have been increasing and appropriate methods for digital equipment identification are needed. We propose a method for device identification using the specific correlation between time drift and CPU core temperature. However, conventional methods require a long time to measure the time drift characteristics because the CPU core temperature depends on the change of the environmental temperature. To solve this problem, we attempted to measure the characteristics using a incubator. The experimental results showed that the proposed method can measure the characteristics in the range of 3 $^circ$C to 55 $^circ$C of the CPU core temperature in a day, while the conventional method took about two months to change by about 10 $^circ$C. Furthermore, it was found that the characteristics show a cubic curve by measuring over a wide range of temperature. It was similar to the temperature characteristics of the frequency of AT-cut crystal used in clock generators, and it indicates the possibility that the time drift characteristics arise from the characteristics of the clock generator. | |
