Problems solved by technology

Current true random number generators usually generate true random numbers based on circuit noise, etc., but the noise is usually small, and it is difficult to directly and accurately measure and quantify it. The usual practice is to measure it after amplification
However, since the amplifier is n...

Embodiment Construction

[0014] In order to provide a high-speed true random number sequence with sufficient randomness, the present invention provides a high-speed true random number generator, which uses liquid Brownian motion as an entropy source, by periodically photographing Brownian motion and digitizing the captured pictures processing to provide high-speed true random number sequences. The present invention is described in detail below in conjunction with each accompanying drawing.

[0015] figure 1 is a diagram of the high-pressure resistant closed transparent liquid pool 100 in the random number acquisition unit. exist figure 1 , the liquid pool 100 is empty and not yet closed. The liquid pool 100 is transparent so as to be photographed by high-speed microscopic imaging equipment. Also, while in figure 1 It is shown that the transparent liquid pool has a certain shape, but those skilled in the art should understand that the transparent liquid pool can be any type and shape of transparen...

Abstract

The invention discloses a true random number generator which comprises a random number acquiring unit and a random number generating unit. The random number acquiring unit comprises a high-pressure-resistant closed transparent liquid pool containing the mixture formed by particles performing Brownian movement, a high-speed microimaging device periodically shooting the internal cross section of the mixture so as to obtain multiple frames of pictures. The random number generating unit comprises a digitization processor for processing the multiple frames of pictures so as to obtain a preliminary random number string A0 and a postprocessor for processing A0 so as to obtain a random number sequence.

Description

technical field [0001] This application relates to random number generators, and more particularly to a true random number generator based on the Brownian motion of liquid molecules. Background technique [0002] Random numbers play an important role in fields such as cryptography, simulation, and integrated circuit testing. A random number sequence is usually a combination of random binary sequences. According to whether it is reproducible and predictable, random numbers can be divided into pseudo-random numbers and true random numbers. Pseudo-random numbers are not really random, they are usually calculated by various electronic devices such as computers, so once you know the generation method and some parameters (such as random number seeds), you can get exactly the same pseudo-random Therefore, for the security of communication, a generator capable of generating true random numbers is required. [0003] True random numbers can usually only be obtained through physical ...
