ONERNG(4) FreeBSD Kernel Interfaces Manual ONERNG(4)
NAME
uonerng - Moonbase Otago OneRNG TRNG
SYNOPSIS
uonerng* at uhub?
DESCRIPTION
The uonerng driver provides support for the Moonbase Otago OneRNG, a USB
true random number generator (TRNG). uonerng reads raw entropy from the
OneRNG and uses enqueue_randomness(9) to add it to the system entropy
pool.
The OneRNG is capable of operating in one of several modes, some of which
are intended for production use and some of which are for testing and
validating the hardware.
uonerng operates in the "Avalanche noise with whitener" mode, which is
also the manufacturer's default mode.

BUGS
The OneRNG permits downloading of the device firmware so that one may
check the firmware's cryptographic signature as provided by the
manufacturer. The uonerng driver does not perform nor support this
action. In order to currently perform such a validation, it would be
necessary to disable uonerng in the kernel and then download the firmware
via the OneRNG's emulated AT modem command set.
