PROBLEM TO BE SOLVED: To generate true and completely uniform physical random numbers without needing random number test at all at a very high speed from 10 Mbits to 1 Gbits per sec and to inexpensively and easily utilize the generated random numbers. SOLUTION: A random pulse signal is generated by detecting a lump of photons radiated from a light emitting diode(LED) 11 by avalanche (amplification type) PIN diode detectors 12, 13. One-bit random numbers are generated by setting up '0' when either one of the detectors 12, 13 detects a lump of photons and setting up '1' when the other detector detects a lump of photons and random numbers of optional bits are generated by enumerating continuous 1-bit random numbers. |
