Embodiments of the invention are generally directed to systems, methods, and apparatuses for a random number generator (RNG) based on oscillator noise. In some embodiments, the RNG buffers effects of thermal noise from two independent oscillators impacted by effects of pseudo-stochastic processes and separates thermal noise from other effects. The RNG may then convert the thermal noise to a stochastic binary sequence based, at least in part, on a digital signal processing algorithm.
