[Cfrg] FourQ draft now available

[Watson Ladd <[e-mail]>]

Dear CFRG,

We would like to announce draft-ladd-cfrg-4q-00, which presents a
high-speed Diffie-Hellman key agreement based on the elliptic curve
FourQ. This scheme is significantly faster than Curve25519, especially
when using endomorphisms. For example, SUPERCOP tests indicate that
one Curve25519 shared secret computation is performed in approximately
156,000 Haswell cycles; our analogous tests with FourQlib indicate
that a shared secret computation is performed in only 56,000 Haswell
cycles (i.e., 2.8 times faster). In some applications, the cost of
public-key operations remains considerable and FourQ is capable of
reducing it, particularly in embedded devices and busy servers.

We hope this draft sees its way to an RFC soon.

Sincerely,
Watson Ladd, Patrick Longa, Richard Barnes
