Embodiment Construction

[0041]A super-expandable high-speed parallel true random number generator of the present invention utilizes a supercontinuum pulse sequence with a high repetition rate and a large random fluctuation in intensity generated by a supercontinuum entropy source as a random number extraction source, Using arrayed waveguide grating 5 to cut the spectrum to get N A narrow-band sub-optical pulse sequence with a high repetition rate and a large random fluctuation in intensity, through N The polarization-maintaining fiber enters the dispersion compensating fiber array 6, and time-domain broadening occurs under the action of the corresponding dispersion compensating fiber, and then passes through another N The polarization-maintaining optical fiber enters the photodetector array 7 and is converted into a corresponding electrical pulse sequence by the respective photodetectors, and finally passes through N The cables enter the analog-to-digital converter array 8, and are quantized into N...

Abstract

A high-speed parallel true random number generator with extra-strong scalability is characterized in that a pulse sequence is inputted to an array waveguide grate by a super-continuous spectrum entropy source, is cut into N narrow-band sub optical pulse sequences, enters a dispersion compensation fiber array generation time domain for spreading, is further inputted to a photoelectric detector array through another N polarization-preserving fibers, is transformed into corresponding electric pulse sequences, finally enters an analog-digital converter array and is quantized into N independent high-speed parallel true random number sequences. The single-channel code rate can reach +Gbps magnitude, at least N=1000 independent parallel true random numbers can be simultaneously outputted, the scalability of an existing parallel true random number generator is increased by at least three to four orders of magnitude, and requirements of modern large-scale parallel computing and high-speed secure network communication can be greatly met.

Description

technical field [0001] The invention relates to a parallel random number generator, in particular a high-speed parallel true random number generator with super-expandability, which is applied in the fields of Monte Carlo simulation, large-scale parallel computing and secure communication. Background technique [0002] Monte Carlo simulation has important applications in nuclear physics, computational chemistry, biomedicine, financial engineering, macroeconomics and other fields. Random number is the cornerstone of Monte Carlo simulation, its quality determines the accuracy of Monte Carlo simulation, and its rate restricts the simulation speed; and the more random numbers consumed in simulation, the higher the quality requirements for random numbers. [0003] With the increasing complexity of the calculation model and the increasing amount of calculations, the current Monte Carlo simulation generally uses multiple processors to execute concurrently, that is, "parallel Monte C...
