NAME
rndtest
- FIPS 140-2 random number generator test monitor
SYNOPSIS
device rndtest
DESCRIPTION
The
driver
``hooks up''
to hardware crypto devices to monitor the
entropy data passed to the
random(4)
subsystem.
This data is periodically tested for FIPS 140-2 compliance and
statistics are collected.
If the harvested entropy fails any of the FIPS test suite, then
it is discarded and testing is continuously applied until
``good data''
is received from the device.
Failures are optionally reported on the console.
The idea for this and the original code came from
An Jason L. Wright .
The
device driver first appeared in
Fx 5.0 .
BUGS
Crypto device drivers must be compiled specially to make use of this driver;
this should not be necessary.
This feature might better be integrated into the
random(4)
subsystem where it can be applied to devices that claim to supply
``pure entropy''
