Non-deterministic random bit generator based on electronics noise

Non-deterministic random bits are needed in many scientific fields. Unfortunately today's computers are very limited in ability to produce them. We present here a method for extraction of non-deterministic random bits from random physics processes, and one practical realization of a physical generator based on it. The method is shown to deliver increasingly good randomness in the limit of slow sampling. A sample of approximately $10^9$ bits produced by the physical generator prototype is subjected to a series of well-known statistical tests showing no weaknesses.
