These test results were produced with 250MiB (2.000.000.000 bits) of random numbers from the device, resulting in 100.000 FIPS blocks with 20.000 bit each - and took two weeks.

100	-	2,25 MiB/s	20,9 KiB/s

FIPS Tests

Multiplier/Mode	raw	failed blocks (SHA-3)	failed blocks /dev/random
0	99999	70 (0,07 %)	81 (0,08 %)
1	-	78 (0,08 %)	73 (0,07 %)
10	-	87 (0,09 %)	89 (0,09 %)
100	-	87 (0,09 %)	95 (0,1 %)
1000	-	78 (0,08 %)	73 (0,07 %)
10000	-	74 (0,07 %)	86 (0,09 %)

The percentage of failed FIPS blocks should always remain below 0,1%.

Run your own tests

Requirements

Make sure you have the following tools installed:

rng-tools (make sure to stop rngd during the test and uninstall/disable afterwards)
ent
dieharder
pv
python (numpy, matplotlib)
infnoise driver

In the header of the script, you can define the test parameters:

declare -a TEST_KBYTES=('25000')
declare -a TEST_MULTIPLIERS=('0' '1' '10' '100' '1000' '10000')

A full test run like this with 25MiB takes almost 2 days, mostly because of /dev/random tests with a multiplier of zero.

This is why by default it performs a reduced run which takes only 1-2 hours.

Tests are run for each combination of these parameters and can be started by running runtests.sh:

$ git clone https://github.com/manuel-domke/infnoise
$ cd tests
$ sudo ./runtests.sh

The output directories will be created automatically.
