Message-ID: <c0951e085764481d8d85637734e2e14b@aptaiexm02f.ap.qualcomm.com> (raw)

Hi Stephan,
NIST SP 800-22-rev1a and NIST SP 800-90B are used together to evaluate the amount of min entropy the source provides, and not to decide if the source has passed the tests or failed. See
https://github.com/usnistgov/SP800-90B_EntropyAssessment
The goal is often to make sure the input entropy is more than the entropy we expect from the output.
Thanks,
Miaoqing

See FIPS 140-2 IG 7.15 which explicitly references SP800-22.
Ciao
