@IsomorphismThm @claucece I didn't even claim that. The paper says "SNOVA uses a weak variant of the whipping technique of MAYO", which is what enabled the new attacks.

@WardBeullens @claucece Weak variant of MAYO! 👊🏻 love that you’re keeping things spicy in the multivariate world

Quite an interesting and super improved cryptanalysis by @WardBeullens of SNOVA, one of the "new" submitted PQC signature algorithms to the NIST process: eprint.iacr.org/2024/1297.pdf Love the smell of amazing cryptanalysis!

This is a very nice website on what women in academia face,as "We start our summary by stating common gender stereotypes such as "women just need to act like men to succeed in academia" or "academia is fair and objective - women are just not good enough". sites.google.com/view/womeninac…

@FouotsaB Keep an eye on ePrint for my next paper SQIsignUltraWide16K_OLED-NorthByNorthwest

They keep coming: SQIPrime eprint.iacr.org/2024/773, SQISign2D-East: eprint.iacr.org/2024/771, adding up to SQISign2D-West eprint.iacr.org/2024/760. Each of these three papers designs a variant of SQISign/SQISignHD that uses only dimension 2 isogenies.

If you are around for the NIST's Fifth PQC Standardization Conference, go check our MAYO poster and talk to Matthias Kannwischer or @WardBeullens . They will presented our paper: eprint.iacr.org/2023/1683 and our poster!

Thanks to all participants of #AfricaCrypt_2023. It was a pleasure to meet all of you ;-)

@mjos_crypto Nice attack 👍😁 If I understand correctly their scheme expects the matrices in the signature to be invertible, but their implementation doesn't check this. So adding the check should prevent the attack, right?

I joined the party and posted a simple break on one of the new signature candidates: ALTEQ 🙃 I'll share some Python code later (I actually wrote quite a bit of code - this attack just turned out to be dead simple.) Message: groups.google.com/a/list.nist.go… Alteq: pqcalteq.github.io

@isogenies @claucece @primaboinca A coaster in the shape of a "save" icon?

@WardBeullens @claucece @primaboinca You need to track down one of these

Our beautiful PQC scheme MAYO is fast and has super nice parameters. Check them out in: pqmayo.org (with new spec, numbers and code) by @WardBeullens @primaboinca Matthias Kannwischer and Basil Hess!

Just looking at the sizes, PQMayo is the most promising submission to the NIST on-ramp I’ve seen. Also the cycle counts are better than expected. Just needs thorough cryptanalysis. 🤞

@isogenies @claucece @primaboinca Unfortunately I haven't yet figured out how to compile for it (or how to get anything on or off the machine) 😅

@WardBeullens @claucece @primaboinca How much faster is MAYO using the super-advanced hardware you won at Eurocrypt 👀

@WardBeullens @primaboinca yes!!

Recently out of the over is the MAYO-sage code: github.com/PQCMayo/MAYO-s…, where we aimed at creating an easy to follow implementation of the PQC scheme MAYO.

@mjos_crypto @asanso Very creative use of the word "fast".

@asanso Sort of, but not really (it is apparently based on an "isogeny hash", a symmetric isogeny primitive.) kpqc.or.kr/images/pdf/FIB… It's pretty wild, as you can imagine; creating a signature takes.. 47 minutes?

Isogenists have had a monopoly on pretty graphs for far too long! (By the way, I don't know why these graphs look the way they do, if you find out please let me know...)

@SchmiegSophie @GarbledCircus CSIDH would like to have a word.

Give me a multilinear map of sufficiently high multilinearity, and a Diffie-Hellman-like assumption on that map, and I can move the world. --Archimedes, probably
