Abstract
A true random number generator including a light source configured to produce randomly distributed photons, a plurality of detection channels configured to receive the randomly distributed photons produced by the light source, each detection channel including a photon sensor configured to detect a receipt of at least one photon during successive integration time-periods and generate an output signal by assigning a value for each integration time-period based on whether at least one photon was received during each integration time-period, a signal conditioning unit configured to condition the output signal of each of the plurality of detection channels and generate a conditioned output signal for each of the plurality of detection channels, and a signal processing unit configured to combine the conditioned output signals and generate a true random number based on the combination of the conditioned output signals.
