US 2021/0344488 A1 · DEVICE AND METHOD FOR GENERATING RANDOM BIT SEQUENCES

Abstract

A device for generating random bit sequences is provided. The device includes at least one Silicon Photo-Multiplier sensor configured to generate a sequence of endogenous random current pulses as a result of an impact ionization driven self-amplification of thermally generated charge carriers to which the at least one Silicon Photo-Multiplier sensor is subject, and a data processing unit configured to receive the sequence of endogenous random current pulses and to determine a random bit sequence to be provided to an end user on the basis of the sequence of endogenous random current pulses received from the at least one Silicon Photo-Multiplier sensor.

A device for generating random bit sequences, the device comprising:

at least one Silicon Photo-Multiplier sensor configured to generate a sequence of endogenous random current pulses as a result of an impact ionization driven self-amplification of thermally generated charge carriers to which the at least one Silicon Photo-Multiplier sensor is subject;
and
a data processing unit configured to receive said sequence of endogenous random current pulses and to determine a random bit sequence to be provided to an end user, on the basis of said sequence of endogenous random current pulses received from said at least one Silicon Photo-Multiplier sensor.

A method for generating random bit sequences, the method comprising:

generating, by at least one Silicon Photo-Multiplier sensor, a sequence of endogenous random current pulses as a result of an impact ionization driven self-amplification of thermally generated charge carriers to which the at least one Silicon Photo-Multiplier sensor is subject;
receiving, by a data processing unit of a device for generating random bit sequences, said sequence of endogenous random current pulses;
