turerandom

now i need design one ture random number generator based chaotic ,but in theory simulation the result cann't pass sp800-22,maybe i need modify my theory equation.help me , can you give me some advice,thanks.
 

turerandom

by the way,i want to see some article about random number generator based thaotic theory ,can you help me .
 

Hi, jodenma,

I am intersted in your work, is it pure logic circuit to implement such a random number generator?

Maybe it is not exactly what you are after but I would use "white noise generator" and just digitalize its output.
If you use 8-bit fast A/D converter you have 256-number random generator, if you use 16-bit A/D you have 65536-number random generator...
 

that's a good idea, but how to sense white noise? using just the ADC, if so, the white noise signal should be amplified .

Another question is how to prove your radom number is true?

Thansk in advance!

I would suggest to use several ring oscillators, where the inverters are done by the weak transistors. The thermal noise will produce a jitter. Assuming you have 4 of them where the typical middle frequency of each oscillator is the prime number, you get a pretty good seed for your random generator.

there are some cellular automatas that generates pseudo-random numbers.

The US NSA says that galactic noise is the best random source. I have seen some systems where the random variation in disk access time was used as the seed. In the thermal noise - ADC approach above I suggest that only the low order bits be used to insure genuine randomness.

To test the results you can do a FFT and see if the spectrum is flat. Another approach is to do an autocorrelation calculation and see if one or more shifts off all give zero value.
 

now more popular ture random generator is based on white noise . the test standard all most is NIST fips140-2 or sp800-2
