摘要： A random number generator (1) comprising, integrated into a single silicon substrate (5), a photon source (2) and a photon detector (3) configured to detect a stream of photons generated by the photon source (2). This random number generator (1) also comprises electronic control means (4) operatively connected to the photon source (2) and to the photon detector (3). The generator provides that the photon source (2) comprises a first SPAD (21), that the photon detector (3) comprises a second SPAD (31) and that the electronic control means (4) are operatively connected to the output of the first SPAD (21) and to the output of the second SPAD (31) so as to receive the output signals (Sout, Sout2) generated by avalanche effects triggered in the first SPAD (21) and in the second SPAD (31) respectively, and are configured to consider as valid for generating a random number only the output signals (Sout2) from the second SPAD (31) generated by avalanche effects triggered in the second SPAD (31) within a correlation time window (T c ), of predetermined duration, starting from the instant in which the electronic control means (4) have detected an avalanche effect in the first SPAD (21).
