[Cryptography] USB hardware token for $2??

[Phillip Hallam-Baker]

I saw this:

http://www.ebay.com/itm/1PC-Digispark-Kickstarter-Attiny85-Mini-USB-Micro-Development-Board-for-Arduino-/282162475109?hash=item41b231b065:g:RIQAAOSw0HVWBMbq

It has an 8 bit CPU with 512bytes of RAM and 2K of ROM. There is a fuseable
link for fixing the firmware.

So...

Any chance one of these could be used as a low cost HSM? Specifically, the
use I would have for it would be to provide a second factor for sensitive
key management operations. I would not store the whole key on the device,
just a share of the key.
