| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, the number of IoT devices has been increasing rapidly, and cryptographic functions such as authentication, key exchange, and encryption are required for secure communication between other communication devices. True random number generator (TRNG) which generate ephemeral key and/or nonce are required to realize these functions. TRNG are required to have the properties of randomness, unpredictability, and non-repeatability. In this paper, we evaluated CIS-TRNG as a physically generated TRNG which utilize the thermal noise on each pixel among CMOS Image Sensor (CIS). We slightly modify the normal readout sequence of CIS image, and CIS-TRNG reads out the signal containing thermal noise twice during the signal from photodiode is cut off. CIS-TRNG generates random number from the least significant bit of the difference between the two pixel readout voltages. We estimated the performance of CIS-TRNG using SP800-90B provided by NIST. | |
