Sažetak
Nondeterministic 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 nondeterministic random bits from random physics processes and one practical realization of a physical generator based on it. Even if processes are weakly correlateed the method is shown to deliver increasingly good randomness in the limit of slow sampling. A sample of approximately 109 bits produced by the physical generator prototype is subjected to a series of well-known statistical tests showing no weaknesses.
