Sorry, what I was trying to say (but fail

The entropy was evaluated by crypto expert, the analysis report show the ADC
with at least 10bits and up to 22 bits of min-entropy for a 32 bits value, we
conservatively assume the min-entropy is 10 bits out of 32 bits, so that's why
set entropy quality to 320/1024 = 10/32. Also we have expl
10 matches
