Method for evaluating an output of a random generator

摘要

A method and an assemblage for checking an output of a random generator are presented. In the method, signatures that are respectively created from a sequence of sampled values are compared with one another.

1. A method for checking an output of a random generator that is constructed as a ring oscillator, including an assemblage for testing, the method comprising:
providing an output of the random generator that is made up of a sequence of sampled values, in which all of the sampled values between a starting value and a final value in one cycle enter into a signature; comparing signatures of at least two cycles with one another; and ensuring that the number of sampled values between a starting value and a final value of the at least two cycles is identical.
