| Abstract(in English) | Frequency injection attacks have been reported as an attack to degrade the randomness of ring oscillator (RO)-based true random number generators (TRNGs). In previous studies, it has been reported that the randomness of RO-based TRNGs can be degraded at multiple injection frequencies, but the relationship between the oscillation frequency of the RO and the effective injection frequency for the attack is not clear. In this paper, we developed a system in which the relationship between injection frequency and randomness degradation in RO-based TRNGs can be evaluated and show resistance of TRNGs with 3-stage and 5-stage ROs against frequency injection attacks. |
