Random number generator

A random number generator includes an entropy source comprising a first digital device arranged to apply to an input signal a first delay value to obtain a first signal and a second digital device arranged to apply to the input signal a second delay value different from the first delay value to obtain a second signal; a sampling unit configured to sample one of the first and second signals using the other signal as reference clock, thereby obtaining a sampled signal; measurement means to perform measurements of the sampled signal's delay difference with respect to the reference clock; a controller circuit arranged to monitor the measured delay difference of the sampled signal and to check the values of the measured delay difference and, once a given condition related to the values is met, to output a configuration signal.
