(English Abstract)
This paper presents parallelization of the random excursions test, which is one of the NIST¡¯s statistical test suite for random bit sequences, and experimental results of measured speedup. Data-parallel property underlies the random excursions test at abstract level of the problem, but the potential cannot be utilized because of the data dependence imposed by the sparse matrix structure adopted by the NIST¡¯s original program. We have exposed data parallelism by transforming the sparse matrix structure. This makes it possible to apply parallel scan and scatter techniques. The parallelized random excursions test shows performance improved by 44 times over the sequential version. If the speed of randomness test would improve to the order of minutes, we can test random bit sequences on the fly when the sequences are generated on a huge scale. This would contribute to level up security of encryption keys.
