Subject: [PATCH v25 03/12] LRNG - /proc interface
Date: Sat, 16 Nov 2019 10:34:12 +0100 [thread overview]
Message-ID: <2476454.l8LQlgn7Hv@positron.chronox.de> (raw)
In-Reply-To: <2787174.DQlWHN5GGo@positron.chronox.de>
The LRNG /proc interface provides the same files as the legacy
/dev/random. These files behave identically. Yet, all files are
documented at [1].
In addition, it provides the file lrng_type which provides details about
the LRNG:
- is the TRNG present
- the name of the DRNG that produces the random numbers for /dev/random,
/dev/urandom, getrandom(2)
- the hash used to produce random numbers from the entropy pool
- the number of secondary DRNG instances
- indicator whether the LRNG operates SP800-90B compliant
- indicator whether a high-resolution timer is identified - only with a
high-resolution timer the interrupt noise source will deliver sufficient
entropy
- indicator whether the LRNG has been minimally seeded (i.e. is the
secondary DRNG seeded with at least 128 bits of of entropy)
- indicator whether the LRNG has been fully seeded (i.e. is the
secondary DRNG seeded with at least 256 bits of entropy)
