Subject: [PATCH 0/2] crypto: Jitter RNG SP800-90B compliance
Date: Sat, 11 Apr 2020 21:34:30 +0200 [thread overview]
Message-ID: <16276478.9hrKPGv45q@positron.chronox.de> (raw)
Hi,
This patch set adds SP800-90B compliance to the Jitter RNG. The
SP800-90B patch is tested for more than half a year in user space
with the Jitter RNG version 2.2.0.
The full SP800-90B assessment of the Jitter RNG is provided at [1].
In addition, the DRBG implementation is updated to always be
reseeded from the Jitter RNG. To ensure the DRBG is reseeded within
an appropriate amount of time, the reseed threshold is lowered.
