NAME
urng – USB Random Number Generator devices
SYNOPSIS
urng* at uhub?
DESCRIPTION
The urng driver provides support for various true random number generator (TRNG) devices connected via USB. urng reads raw entropy from the device at a (hardware dependent) interval and stirs it into the system entropy pool with enqueue_randomness(9).
HARDWARE
The following devices are supported by this driver:
- Araneus Alea I and II
-
Capable of delivering 100kbit/sec of hardware-generated entropy.
- Altus Metrum ChaosKey 1.0
-
This device is capable of providing entropy at 10Mbit/s.
