Dear all,

Revision 04 of the AES-GCM-SIV draft
(https://tools.ietf.org/html/draft-irtf-cfrg-gcmsiv-04) has just been
published. This contains only tidy-ups from revision 03—no substantive
changes have been made.

Most importantly, it now references a paper
(https://eprint.iacr.org/2017/168) by Shay and Yehuda in which they
give precise security bounds for AES-GCM-SIV. Specifically I'd like to
highlight to the group theorem six (which gives those bounds) and
section 5.3 (which gives concrete values of those bounds at a number
of locations in the configuration space).

In light of previous discussions in the working group, section seven
includes some remarks about the meaning of nonce-misuse resistance.

(Comments about the paper, including sightings of typos, are welcome
to be sent to us directly; no need to clutter this list with them.)


Cheers

AGL
