抜粋

True random number generators (TRNGs) based on ring oscillators (ROs) are employed in many devices because they can be constructed with a simple circuit structure. Many systems are affected if an RO-based TRNG is attacked, and its security is degraded. Conventional attacks against RO-based TRNGs reduce randomness using direct physical access to the target device and/or modification/invasion of the device or the equipment on which it is implemented. However, depending on the physical location of the device and its tamper resistance measures, directly accessing the device or operating/modifying the implementation may not be easy. This study introduces a noninvasive attack against RO-based TRNGs. In this attack, we intentionally induce sinusoidal electromagnetic waves in a TRNG and estimate the change in its randomness under this interference by observing the signal leaked from the TRNG from a distance. We also consider countermeasures against noninvasive attacks on TRNGs.
