Russell: Sources of Randomness for Userspace
Posted Mar 30, 2012 21:43 UTC (Fri) by khim (subscriber, #9252)
This argument can be used to discourage AES-NI, but unfortunately it does not fly when we are discussing RNG. Software literally can not create randomness. It's deterministic - that's the whole point. Sure, different pieces of hardware have different reliability WRT to predictability, but some hardware is always needed.
As this point we are down to the randomness generated by Ethernet, Keyboard and Mouse and I fail to see where the idea that Ethernet (especially emulated one in VM) can generate better randomness then dedicated hardware comes from.

After seeding, I want my prng to be software, not hardware.
