@fhe_org Just checking: Are the submissions anonymous? I’m so looking forward to joining this year!

[Jelle Vos @JelleVVos]

@bert_hubert Hmm wat vaag verwoord… Denk je dat ze bedoelen om een nieuwe Nederlandse CA in het leven te blazen of misschien een soort Nederlandse NIST?

[Jelle Vos @JelleVVos]

@rossjanderson Encrypted data are not like castles: they can be stored until a ‘heffalump’ (quantum computer) emerges and be broken retroactively. Castles, on the other hand, can be fortified: they cannot be retroactively breached.

Still, no one knows for sure if ‘heffalumps’ will exist!

[Jelle Vos @JelleVVos]

@ZekiErkin @GSmaragdakis @tudelft @CyberSecTUDelft Thanks Zeki! Let’s also give some credit to @CelioM6, and I want to thank @realFWDekker for all the fruitful conversations we had about this topic. It’s been an amazing experience!

[Jelle Vos @JelleVVos]

@SmartCryptology @zama These talks sound truly amazing! I’m sad to miss them. Do you know if it’s possible to find some of the slides online?

[Jelle Vos @JelleVVos]

@CionnRatz @tudelft If we do we should have LaTeX rendering! 😁 I would join in a heartbeat. Otherwise I am considering joining https://t.co/LI2HeoYeWo.

[Jelle Vos @JelleVVos]

@m_ou_se @sdowney Until this (https://t.co/jB51O7L7wM) is stable we may have to limit the compiler to a million instructions 😛 Although I suppose fewer instructions means even more safety!

[Jelle Vos @JelleVVos]

@daniel_a_vos The data and a baseline solution are now online! Check them out at https://t.co/elvuyNdBfT. 😁

[Jelle Vos @JelleVVos]

If you are a fan of homomorphic encryption, then try your hand at the secure biometrics competition @daniel_a_vos and I are organizing! Registrations opened today and the data becomes available on Friday next week. (And yes, it involves dogs 🐕)

@cronokirby We brainstormed about this shortly with some people at #tpmpc, I’m very curious if there are any schemes that do not make it prohibitively expensive when doing rotations, bootstrapping, etc. 😄

[Jelle Vos @JelleVVos]

It’s an amazing event so far! Thanks for organizing this (and for the fabulous MPC song 🎶 ) @AarhusCrypto

[Computer Science at Aarhus University @csaudk]

This week, @AarhusCrypto is hosting the 2022 Theory and Practice of Multi-Party Computation Workshops at the department - gathering experts from all over the world. Unable to attend? Follow the live stream ➡️ https://t.co/yLcd8c7wab

In this work we show how to construct multi-party private set operations that function strictly in a star topology 🌟. All protocols rely on the same primitive: A multi-party private OR protocol. Our weapon of choice is ElGamal over elliptic curves.

#ePrint Fast Multi-party Private Set Operations in the Star Topology from Secure ANDs and ORs: J Vos, M Conti, Z Erkin https://t.co/EHsjuyWDBY

[Jelle Vos @JelleVVos]

@cronokirby Interesting abstraction! And the security proof seems believable 😆

[Jelle Vos @JelleVVos]

@cronokirby @CryptoHack__ I recently learned a trick that made safe prime generation a lot faster from studying the openssl code! It turns out you can do some local sieving for (almost) free. I implemented it here (go easy on the crate, it’s a rough first version): https://t.co/kSThiUmqvN

[Jelle Vos @JelleVVos]

@ZekiErkin Good luck!! 🙏🏻

[Jelle Vos @JelleVVos]

@cronokirby I guess it helps seeing seasonal effects, but I’m not a fan either

[Jelle Vos @JelleVVos]

A happy Christmas present 🎁 is that our paper about multi-party private set intersections was published in the IEEE TIFS journal! (with Aslı Bay, @ZekiErkin, @xotoxot, and Simona Samardjiska)

Check it out here [open access 🔓]:

[Jelle Vos @JelleVVos]

While the conference had to be organized in a reduced form, I am very happy to present our work at WIFS 2021! (Thanks for the photo @ZekiErkin)

I have written a thread about this work before for those who are interested. 🙂 https://t.co/8mDkTcRtZV

[Jelle Vos @JelleVVos]

I am happy to announce the first paper on which I am the first author! 🎉 Our paper titled "Compare Before You Buy" will be published at IEEE WIFS. @chr_doerr @ZekiErkin

A short thread 🧵

[Jelle Vos @JelleVVos]

@kaepora @RealWorldCrypto I’m interested!

[Jelle Vos @JelleVVos]

@DucasLeo @BenjWeso Congratulations! 🎉 Would this require us to change the way we choose quantum-secure parameters for e.g. RLWE-based FHE cryptosystems? It is my current understanding that the homomorphic encryption standard uses the lwe-estimator for both LWE and RLWE.
