U2F stands for Universal Second Factor, see also
http://en.wikipedia.org/wiki/Universal_2nd_Factor

You can find the protocol specification on
http://fidoalliance.org/specifications/download/

I’ve done a presentation at our local computer club, you can find the
slides here:
https://www.noname-ev.de/w/File:C14h-u2f-how-security-keys-work.pdf —
they contain a pretty high-level and easy to understand description of
U2F.

Is that what you were looking for? If not, let me know :).
