Raspberry Pi internal hardware random number generator [Project]
posted May 27 2014 13:58.34 by spic0m




The Raspberry Pi includes a hardware based random number generator that promises to provide the fastest, best source for the typical users to obtain cryptographic quality random numbers in an extremely small portable package.

If you read the whole detailed analysis of the samples, the data behaves exactly as we would expect a true random number generator to perform, it occasionally fails some tests, but those failures are not duplicated on subsequent samples indicating the failures are just examples of random chance as one would expect. Overall the built in hardware random generator on the Raspberry Pi appears to perform quite well, and at 1 million bits per second is likely the most affordable true random number generator available to the general public.
