Abstract
Random numbers are generated according to a variety of solutions. A particular solution relates to a method for generating the random number. A common start signal is provided to each of a plurality of inverter components of a ring oscillator circuit. This causes the ring oscillator circuit to enter a metastable mode. At least a first bit and a second bit of a random number are both generated in parallel. The parallel generation of the bits involves the generation of the first bit from entropic properties of a signal of a first one of the plurality of inverter components and the generation of the second bit from entropic properties of a signal of a second one inverter components.
