Study Of Technologies For Random Number Generator

In present day random numbers are widely applied in many areas. In this paper, we show some researches about technologies of random number generator:We propose a brand new scheme of all-optical parallel truly random number generators. We first utilize the random lasers as the random source and organize an all-optical system to extract random signals and manage them to generate random numbers. We couple the intensity of light with frequency spectrum by phase contrast system and use the λ/4DFB arrays to realize all-optical sampling. In the post-processing section, we design an all-optical XOR gate to improve the randomness of random numbers. Finally, we briefly discuss the measurement of light and propose a new scheme of random numbers generators.
