摘要

A system for random number generation includes a laser pulse driver; a laser diode emitting laser pulses; a fiber-optic unbalanced interferometer transforming laser radiation phase noise into amplitude modulation; an optical circulator/isolator that is used to prevent unwanted feedback into a laser cavity; a photodetector that detects the laser pulses from the interferometer; a digitizer that digitizes an output of the photodetector; a statistics control (SC) block that is used to calculate the probability density of the photodetector's output and to define a parameter Γ that is related to a classical-to-quantum noise ratio and allows estimating random operation and providing attack resistance of the system; and a processor that receives the digitized output from the digitizer and outputs a true random bit sequence.
