#IACR #Cryptography Does anyone knows where PKC 2026 will be held ? IACR website does not yet say, but I'm pretty sure it is already settled.

"Towards Optimally Secure Deterministic Authenticated Encryption Schemes" was presented today at #IACR #Eurocrypt 2025 in Madrid.

This morning our researcher Robin Geelen presented "Fully Homomorphic Encryption for Cyclotomic Prime Moduli" at #IACR #Eurocrypt 2025 in Madrid.

First Leg finished on the way to #iacr #eurocrypt . Rail construction between Göteborg and Hamburg so ferry it is

Our paper Leap: A Fast, Lattice-based OPRF With Application to Private Set Intersection is finally public (https://eprint.iacr.org/2025/333) and will be presented at #IACR Eurocrypt 2025!

My personal favourite contribution is that we show that lattice-based OPRFs are faster than the elliptic-curve based 2HashDH construction. Our proof-of-concept implementation (though unoptimized and non-constant-time for now) shows promising computational efficiency. Since we obliviously evaluate the heuristically-secure OPRF SPRING, the PRF part of the OPRF is also blazingly fast. This gives rise to efficient post-quantum computation that could potentially beat classical computation.

last year at #rwc2024 there was no streaming, intentionally. the reason they want people to come in person instead of sitting in front of a screen. sounds crazy? apparently companies argue if there is a stream they won't $$$ pay the travel for employees (what about people who are not employees? no idea). not this year though, i was told there will be #streaming. let's hope, for those unfortunate who cannot be there. #iacr

i want to go to #rwc2025 but am a bit bummed that the #iacr only accepts payment via credit cards. that is a serious gatekeeper. and when i ask for an alternative option i'm asked if would not reconsider and find a way to use a credit card. this makes me feel very sad, and i wonder where all the cryptographers disappeared that were into anonymous or payments from a less monopolized system. and no i'm not arguing for any #crapto like bitcoin, simple cash or sepa transfers are totally ok)

Registration for the 2025 Workshop on Real World Multiparty Computation (RWMPC 2025) is now open!

RWMPC 2025 will bring together MPC practitioners and enthusiasts to discuss how MPC is being deployed and used today to solve real world problems. The workshop program will consist of invited and contributed talks on MPC-related topics such as real-world deployments, use cases, standards, security, formal verification, legal/policy implications, and more.

RWMPC 2025 is organized and hosted by the MPC Alliance in cooperation with the IACR.

Let me bury my head by focusing on the professional consequences. I think the #IACR has to rethink it's policy of always hosting a yearly conference in Santa-Barbara.

💥 ❤️ 📣 New updated revision of the #Shufflecake research paper 📣 ❤️ 💥 available on #IACR #Eprint https://eprint.iacr.org/2023/1529 and #arXiv https://arxiv.org/abs/2310.04589 (still not out, scheduled next Monday) which tracks changes up to software v0.4.5 and clarifies that the described scheme is the `Legacy' version of Shufflecake, and that future versions might deviate from the paper (*ah-ehm*... Lite *cough*). Also typo fixes and language improvements.

Last week, I was delighted to attend
#FSE2024 in Leuven, Belgium, where I had the privilege of presenting our papers. Beyond the presentations, it was a nice opportunity to meet and exchange ideas with many leading experts in our field, initiating potential collaborations.

@stf The videos are posted to the #iacr youtube channel as a playlist after encoding/processing: https://www.youtube.com/@TheIACR

i was just told that it is deliberate that #realworldcrypto is not #streaming the event. apparently this is a controversial discussion every time. but they also decided next year will be streamed again... what i wonder though, why the secrecy? why not say it out on the webpage, sorry folks no streaming because of <reason>.

anyway, looking forward to the recordings, and next years streaming

#iacr

seriously considering sponsoring live streaming (and archival) for the next #rwc when it is in europe... if anyone is interested, pls chip in, we have the hw and the personal we only need to cover travel and accommodation.

#realworldcrypto #iacr

can't believe it that there is no live stream for #realwordcrypto - #iacr please i beg you think of those that are not privileged to be there in person...
