Dear Ivaylo:
I would like to ask for a presentation slot for the COSE/JOSE meeting
Wednesday next week.
Title: code points for fast-verification friendly ECDSA
Presenter: Rene Struik
For context, please see my email of Tue Nov 2, 2021 below.
Best regards, Rene

Dear Ivaylo:
I presented a mechanism for putting ECDSA signatures into a format
that facilitates verification speed-ups, both in single-verify and
batch verification settings [1]. While this technique (known for more
than 1 1/2 decades) is generally applicable, I believe this would be
especially useful to implement with JOSE and perhaps COSE right now,
given Covid-vaccination records using ES256 in the smart healthcard
specifications [3] (proposed with IATA, etc.). For the main idea, see
[1]. For a JSON Web signature example, see [2].
Do you think I could briefly present? I would like to ask for a code
point for JOSE and others down the road.
I think I could simply present the example of [2] and some applications.
Best regards, Rene
