An interesting question (for me, at least) is: how will I know that the
hardware RNG is really producing stuff based on thermal noise, and not,
say, on the serial number, some secret known to Intel, and a PRNG?
You don't. More to the point, there is no way
to test a random number generator within the
small (and shrinking) automated test time that is
part of the production line. The falsifiable
hypothesis for a multiplier, say, is that it
gets the right answer. The falsifiable hypothesis
for a RNG is a long slog through volumes of output.
All the production line can say is "turns out a
stream of bits that ain't all ones or zeroes."
I'd imagine that failed devices will be common
enough to be a intellectual curiousity, at least.
