Dear COSE working group members,
Do you have proposed agenda items for our session at IETF 113 in Vienna? If
so, please reply-all to this note. Include a title, the presenter(s), and
proposed amount of time you’d like.
We have a slot for 13:00-14:00 on Monday Afternoon.
I’m looking forward to seeing many of you in Vienna!
I don't yet have an I-D but if you want I could talk 15 minutes about a work
item that combines COSE algorithms, FIDO/CTAP2, and a new CBOR based signature
container. The target is primarily payment authorizations.
An existing solution featured in Chrome and Edge browsers uses a JSON based
scheme:
https://w3c.github.io/secure-payment-confirmation/#dictdef-collectedclientadditionalpaymentdata
I'm proposing using a CBOR based solution:
https://fido-web-pay.github.io/specification/crypto.html#4.3
Since COSE isn't compatible with FIDO signatures, a CBOR based signature solution needs
to either enhance COSE or start-off from scratch. I opted for the latter approach (which
later this evolved into a an alternative to COSE for "regular" applications as
well).
Thanx,
Anders
