Abstract
A synchronized true random number generator (SRNG) includes a pulse source that provides a synchronized pulse signal synchronized with a known time, an oscillator to make a clock signal, a time synthesizer, and a triggerable true random number generator (TRNG). Another embodiment includes a plurality of independent triggerable TRNGs, separated by a separation distance, that produce free TRNG output. A separation distance is a distance greater than the product of the speed of light (C) multiplied by the generation period. A generation period of a TRNG is the period from the start of generating a random number until the random number can be determined. A triggerable single-photon-detector TRNG comprises first and second single-photon detectors, a light source, first and second pulse-generator circuits, and a first-pulse detector. A triggerable photon-shot-noise TRNG contains a photonic detector comprising two photodiodes connected back-to-back, and light source (e.g., an LED) providing illumination to the two photodiodes; a current-to-voltage converter; an amplifier; and a comparator for converting the amplified voltage noise to a binary random bit output.
