Appraisal of a Random Bit Generator Utilizing Smartphone Sensors as Entropy Source. (arXiv:2208.11370v1 [cs.CR])

We aim to access entropy sources available within smartphones in order to
construct and evaluate a random number generator which is competitive in
comparison with existing and proven random number generators. A prototype
utilizing the herein proposed algorithm shall generate data that can be tested
against the Statistical Test Suit provided by NIST. Although our initial
intention of using cosmic radiation failed, we were able to extract randomness
from incoming video and audio sources. We found that it is possible …
