Subject: [PATCH v25 06/12] LRNG - add SP800-90A DRBG extension
Date: Sat, 16 Nov 2019 10:35:31 +0100
Message-ID: <2014245.ZDxk4MLLqQ@positron.chronox.de> (raw)
In-Reply-To: <2787174.DQlWHN5GGo@positron.chronox.de>

Using the LRNG switchable DRNG support, the SP800-90A DRBG extension is
implemented.

The DRBG uses the kernel crypto API DRBG implementation. In addition, it
uses the kernel crypto API SHASH support to provide the hashing
operation.

The DRBG supports the choice of either a CTR DRBG using AES-256, HMAC
DRBG with SHA-512 core or Hash DRBG with SHA-512 core. The used core can
be selected with the module parameter lrng_drbg_type. The default is the
CTR DRBG.

When compiling the DRBG extension statically, the DRBG is loaded at
late_initcall stage which implies that with the start of user space, the
user space interfaces of getrandom(2), /dev/random and /dev/urandom
provide random data produced by an SP800-90A DRBG.
