About this paper
Maciej Skorski, Nathalie Bochard, Licinius Benea
The authors analyze security of oscillator random number generators under white and flicker frequency noise, modeling both with fractional Brownian motion and conditioning on the entire phase history. Their method shows five-sample estimates can overstate leftover variance by 23%, yielding 0.974 rather than 0.99 bits of min-entropy. Hardware-calibrated rates are predictions, not demonstrated throughput, under the assumed noise model.
