They also published their own curve (a 256 bits GF(p) one), named FRP256v1 (
http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024668816).
But since they don't provide any detail on the parameters' choice, and the
use of this curve isn't mandatory at all, I prefer the Brainpool ones.
They're also pushing for ECKCDSA adoption, by asking HSM manufacturers to
include this mechanism. I don't know anything on this.
