True random number generators (TRNGs) based on ring oscillators (ROs) are employed in many devices because they can be constructed by logic gates. If a RO-based TRNG is attacked and the randomness is reduced, the system security is affected. As physical attacks on the TRNG, conventional studies mainly focused on reducing the uniformity of random numbers. On the other hand, the feasibility of an attack against the unpredictability of random numbers, which is one of the requirements for randomness, has not been fully discussed. If some of the output bits can be estimated, the entropy of random numbers used for security can be significantly reduced, which is a serious security threat. In this paper, we investigated the possibility of an attack against the unpredictability of TRNG. Specifically, we evaluated the feasibility of estimating the output bits by using the frequency injection attack, which is used to degrade uniformity, and observing changes in TRNG operation caused by attacks. |
