Abstract: A random number generator includes a photon source and one or more photon detectors of the SPAD type (311) configured to detect a photon flow equal to ?, wherein the photons are generated by the photon source. The random number generator furthermore includes an electronic sampler. The electronic sampler is configured in such a way as to detect the arrival time t of a photon incident on each SPAD photon detector (311) for each one of the observation windows Tw, and are also configured in such a way as to convert the arrival time t into a binary sequence. In the generator of the invention the photon source and the electronic sampler are configured in such a way that the product ?*Tw is lower than or equal to 0.01.
