Generation of physical random numbers with a variable-capacitor parametron

In the present study, a random number generator which physically produces nonperiodic uniform random number was developed using the parametron principle. The parametron is an oscillation circuit at one‐half of the excited frequency. The phase of the parametron cannot be predicted because it depends...

Description
Summary:In the present study, a random number generator which physically produces nonperiodic uniform random number was developed using the parametron principle. The parametron is an oscillation circuit at one‐half of the excited frequency. The phase of the parametron cannot be predicted because it depends on the noise in the parametron circuit. The random number was generated by detecting the unpredictable phase. The randomness of the data generated by the present method was confirmed by the spatial distribution and by statistical random tests. © 2002 Wiley Periodicals, Inc.
