Dear all, Kim Laine has something to say about genus three curves. I don't know what it is, but will report when I hear it in two weeks.
On the genus 1 front, what sort of properties do implementors expect from point formats? Mike Hamburg argues it's fine to not have a bijection, so long as round tripping from point to encoded format to point gives the same point on a big encodable subset (think E[q](K), not all the rational points. That is, we throw out some small-order points). I'm starting to come around to this idea, but some of the formats are just wonky and require quite a bit of thought to understand or don't work for curve25519, or both. Does anyone have explicit formulas for clever formats?
