New nonparametric methods were developed for verification and monitoring of quantum randomness based on the ranged correlation function (RCF) and a sequence of the ranged amplitudes (SRA). RCF analysis of different topology subsamples from the raw data of the prototype of a quantum random number generator on homodyne detection was carried out. It was shown that in the real system there are weak local regression relations, for which it is possible to introduce a robust criterion of significance. Precise SRA identification of the long samples statistics was carried out. The obtained results extend the traditional entropy methods of the useful randomness analysis and open the way for creation of new strict quality quantum standards and defense for physical random number generators.
Keywords: ranged correlation functions, RCF defense, quantum randomness, physical random number generator.
