#award Announcing the 2026 IACR Fellows iacr.org/fellows/ Congratulations to everyone!

@AlgebraVic @SoosMate @veorq @mccurley People end up writing papers for for non expert reviewers, trying to teach the reviewer the topic before describing their result.

@AlgebraVic @SoosMate @veorq @mccurley May be the reviewers were experts on the topics of the papers they were reviewing? Today, you join a big Crypto conf PC, you get 20+ lengthy papers to review in one month, of which if 5 are in your area of expertise then can count yourself as lucky.

I don't normally post to X, but this is the distribution on the number of pages of papers submitted to crypto 2026. The average number of pages is 50. There were 752 papers, of which 22 have more than 100 pages. Peer review anyone?

Main ingredient: orientations don't like inert primes because they (orientations) bring no advantage for computing isogenies with inert prime degree.

Quaternion signatures for isogeny group actions: showing how to adapt SQIsign and PRISM to the group actions setting, unleashing WaterSQI and PRISMO signatures that come with a tremendous speed-up over CSI-FiSh style signatures. ia.cr/2025/1737

Thanks @realmadrid @realmadriden for the birthday 🎂 wishes! ¡Madridista para siempre!

I mean as a sub-reviewer...

It saddens to spend time reviewing a paper, then to neither be able to see the other reviews nor take part in the discussion on that paper! Program Chairs should always enable this (and choose a reviewing platform that allows them to).

The second Levchin Prize goes to the CADO-NFS team: Emmanuel Thomé, Pierrick Gaudry, and Paul Zimmerman! Congratulations! #realworldcrypto
