ualea —
Araneus Alea II USB TRNG
ualea* at uhub?
The
ualea driver provides support for the
Araneus Alea II, a USB true random number generator (TRNG). It delivers
100kbit/sec of hardware-generated entropy.
ualea reads raw entropy from the Alea II
and uses
add_true_randomness(9)
to add it to the system entropy pool.
The product documentation states that the USB interface used by the Alea II is
the same as that used by its predecessor the Alea I; theoretically this means
that the Alea I should work but this has not been tested.
