Because that won't tell me if you are performing entropy extraction.

OK, if you think my Jytter TRNG is weak,
I did not say it was weak. I said Jytter (and any other algorithm) is
deterministic when run on an entropy free platform. This is a simple fact.
All platforms have entropy.
If they boot from a physical

The question is, does all this entropy show up in Jytter? I rather think it
does.
the question is: is your adversary nature, or human nature?

All, in the interest of clarity:
1. Let's do the math. Let's assume that we have a really dumb entropy
extractor which waits around for 128 interrupts to occur. It just sits in a
loop sampling the timestamp until this criterion is satisfied. It saves all
these time stamps to a big chunk of

in your case, hash 128+N samples to get, say, 127.99 bits of entropy per
hash output. N is small, under 20 I think.
Yeah this certainly inspiring with respect to milking decent entropy from
coldbootish environments. If we assume the use of a good hash, then the
problem reduces to one of asking
