Yuriy - I can work with you to write the necessary text for UAF to register the
additional algorithms it needs. I'll talk with you off-list about it.

I would not do the private range version below if you are going to publish in
FIDO docs. This is really meant for completely closed and experimental and not
for any public standards use.

Hi Yuri,
The COSE specification probably should not change to accommodate this. The IANA
COSE algorithm registry should be used instead.
There are several options:
- Write a standards track IETF document and get it set in the IANA COSE
registry<https://www.iana.org/assignments/cose/cose.xhtml>.
- Write a specification (presumably public) and get it set IANA COSE
registry<https://www.iana.org/assignments/cose/cose.xhtml>.
- Use an identifier in the private range and publish it only in FIDO docs.

Hey guys. I work for FIDO Alliance. We are currently selecting a list of curves
we going to support. We want to support secp256k1 in COSE, as we are already
supporting it in UAF, and we have companies who really want it.
I know that in security considerations you've said that there is possibility of
collision of the signatures from k1 and p1, but the chances of such thing
happening are enough low for it to be ignored.
We are proposing adding secp256k1 into list of curves, in section 13.1 with
value 8
