摘要 |
In a random number sequence sharing apparatus, a reception unit receives a radio signal including a radio wave from a pre-designated radio star at a pre-designated observation time, a sending unit sends the received radio signal to another random number sequence sharing apparatus, an acceptance unit accepts a radio signal sent from the another sharing apparatus, an analysis unit separates the two radio signals into a plurality of independent components by independent component analysis, a selection unit selects two independent components temporally different by difference in time required for the radio wave to arrive at both sharing apparatuses from the radio star, a sampling unit averages the two selected independent components after adjusting the temporal difference and bit-samples the average, and an output unit outputs a sequence of the bit samples as a random number sequence to be shared.
