Dear colleagues:
A slight update of my curve representation draft.
Based on some discussions in the hallway at IETF-105, I added another
example (alternative representation of the BitCoin curve secp256k1
[Annex M]). I also added a description of how to represent curve points
pseudo-randomly and added verbiage to the privacy section to alert
people about this. These changes are informational (I did not ask for
code points for such a censorship-prevention representation [I could,
but that is up to the group at large]).
I believe this draft is ready (in fact, I thought it was in May: the
material above is just bonus material).
If you want to discuss with me at IETF, please do grab me in the hallway
(I have to leave 3.45pm).
Rene

Title : Alternative Elliptic Curve Representations
Author : Rene Struik
Filename : draft-ietf-lwig-curve-representations-08.txt
Pages : 72
Date : 2019-07-24
Abstract:
This document specifies how to represent Montgomery curves and
(twisted) Edwards curves as curves in short-Weierstrass form and
illustrates how this can be used to carry out elliptic curve
computations using existing implementations of, e.g., ECDSA and ECDH
using NIST prime curves.
