Spotlighting Greyhound đŸ, the new amazing work from @KhanhCrypto and @gregor_seiler!
A new super fast and compact polynomial commitments from standard lattice assumptions!

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".

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!

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

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!

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

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...)

Since 1969 Strassenâs algorithm has famously stood as the fastest way to multiply 2 matrices - but with #AlphaTensor weâve found a new algorithm thatâs faster, with potential to improve efficiency by 10-20% across trillions of calculations per day! dpmd.ai/dm-alpha-tensor

There's a new bi-weekly seminar on an oddly specific topic in town! @KrijnReijnders and I are happy to announce that the Isogeny Club will start this fall! Spread the word!

The funniest part is how the email tries to list the pros/cons of each scheme, and included "can be broken in a weekend with a laptop" as the cons for Rainbow.
Seems like a dealbreaker to me!

I wrote a brief summary of @WardBeullens's Rainbow attack! This is probably the most excited I've ever been reading a paper: priv.pub/posts/rainbow-attacâŠ
