Dear colleagues:
I slightly updated the draft to address Mohit Sethi's comment [1] on
trade-offs between code reuse and computational efficiency. To this end,
I added a little section (now Section 6) on "implementation
considerations" - see[2].
As already suggested in [3], I did not give an explicit computational
cost comparison, since this is highly device and application dependent
and alone would not do justice other considerations that come into play
when deciding on a crypto implementation strategy.
Best regards, Rene

Title : Alternative Elliptic Curve Representations
Author : Rene Struik
Filename : draft-ietf-lwig-curve-representations-05.txt
Pages : 62
Date : 2019-05-15
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.
