Abstract (in Japanese) (See Japanese page) 
(in English) True random number generators (TRNGs) based on ring oscillators (ROs) are employed in many devices because they can be constructed by logic gates. The randomness of TRNG must be uniform, unreproducible, and unpredictable, and the quality of random numbers is very important in cryptographic protocols. If the unpredictability of TRNG is reduced and the output bits of TRNG used in the cryptographic protocol can be estimated, the security of the entire system can be significantly reduced. The authors showed the possibility of predicting the output bits by a side-channel attack against TERO-based TRNG, and proposed its countermeasures at SCIS2020. In this study, we performed a statistical test of random number sequences generated by TERO-based TRNGs that are resistant to side-channel attacks and mathematically analyzed the effectiveness of countermeasures against random number bias.
