Dear colleagues,

We kindly ask you to agree to add two Twisted Edwards curves with p =
2^{512}-d and p = 2^{256}-d to the proposed draft.

If you see it possible, we can generate these two curves ourselves –
completely with accordance to the method described in the current draft
(including deterministic "rigid" "non-random" method of curve search
process).

It can be done very quickly – we have a big interest in it, since only
curves with 2^{254}<q<2^{256} and 2^{508}<q<2^{512} are allowed with our
GOST and we want our Russian PKI standards to be as much connected with
international ones as possible.


P.S.: Description of our GOST can be found in ISO/IEC
14888-3:2006/Amd.1:2010(en) Information technology — Security techniques —
Digital signatures with appendix — Part 3: Discrete logarithm based
mechanisms AMENDMENT 1: Elliptic Curve Russian Digital Signature Algorithm,
Schnorr Digital Signature Algorithm, Elliptic Curve Schnorr Digital
Signature Algorithm, and Elliptic Curve Full Schnorr Digital Signature
Algorithm.
