True Random Number Generator using atmospheric noise

I have to build an One Time Pad system and for that, I have to build my own TRNG. I want to know how to make record atmospheric noise and use that to generate random numbers. I've tried so far to record a .wav file and read it in Java, but the…

Getting true random numbers from secure enclave in iPhone?

Is it possible to get true random numbers from the secure enclave in the iPhone? I read the secure enclave includes a TRNG. I'm not sure if it's possible to use this to get random numbers or if it's for internal use of the secure enclave only. Any…

Dieharder dab_monobit2 test fails - all other tests pass - TRNG

I am currently testing some RNG numbers from a TRNG using the dieharder test suite. I got around 380MB binary test data from the TRNG and all tests pass except one test - the dab_monobit2 test (test 209) and I just don't know why. As far as I…

Is Jericho Comms TRNG reliable?

I'm looking for a method to generate true random bits/numbers on smartphones. Create a custom TRNG seems to be tricky and a lot of people suggest to trust in already existing ones, widely tested and approved. But I've found Jericho Comms, that uses…

Can machine learning models be used to predict TRNG output?

As far as I know, in order to train a machine learning (ML) model, both inputs and outputs of a train set should be known. Then, given a new input, the ML model tries to predict the output. With TRNGs, only the output is known (there is no input).…
