1. 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 generated endogenously by direct or trap assisted band gap tunneling, without relying on an exogenous source of pulses external to said at least one Silicon Photo-Multiplier sensor; 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.
