Julian Loss

Congrats to Dr. Benedikt Wagner for receiving the @helmholtz.de Doctoral Award! 🎉 His dissertation was supervised by Dr. @julianloss.bsky.social at CISPA. Benedikt is now bringing his cryptographic expertise to the Ethereum Foundation in Switzerland.
Wishing him continued success and inspiration!

Congratulations Tibor!!

We give a nearly optimal algorithm for the parallel broadcast problem for the t<n/2 setting using *only basic public key crypto*. Our protocol has major potential for making MPC and VSS scalable without relying on more advanced primitives. At Crypto 2025!

New paper at Crypto 2025!

We revisit one of the famous works of King et al. on leader election/consensus and show that the original paper’s proof has several major gaps. Although we aren’t able to prove the original protocol secure, we suggest a suitable modification along with a full proof.

We present the first three-round Schnorr threshold signature scheme with security against t<n adaptive corruptions in the plain ROM. At Crypto 2025!

What’s up, long time no see.

I decided to move here after Twitter/X became unusable, but I realized that this was actually a great opportunity to get off of social media for good, read a book, go outside, and make some new friends.

Anyway, I’m back; what did I miss?

Crypto Eprint just broke 2k submissions in one year for the first time. Great to see the field continue to grow.

I live in Germany which is typically reluctant to adopt digital/electronic solutions to common tasks, payments in particular. However, QR-code bills have become widely popular here and I think that’s a really great development as they are so convenient. How widely are these used in other countries?

I heard a lot of restaurants there serve delicious Kol Kattas

Yeah, my HM pace dropped by 6s/km after switching to carbon plate

Make this your episode of personal growth for 2024

unprecedented

But what is the point of making this assumption explicit? Why don’t you just let the code assume it implicitly? Or is this just meant to make the code easier to follow for someone reading it?

You know, that argument also works in the other direction 😅

What is the upside to assume y=9 over just hardcoding y=9?

Well, yes and no. The hope is that you might somehow use the algebraic structure of the field to show something

Why not try to write a proof instead?

hey, it’s getting pretty spammy now on my timeline and I’ve yet to find a good way to mute these posts 😅. i’d be sad if the first person I had to block here were a fellow cryptographer

what’s going on here

The subject line is also FUBAR, I had to keep myself from bursting into spontaneous laughter in the TCC session on mathematical foundations of cryptography I’m sitting in

Enjoying Milan on a cold morning. What’s up @suinetwork.bsky.social

I think it was? Although I can no longer see it, because I’ve been blocked for pointing this out. If you’re not careful, you’ll be next 🤣

lol what did I do

“thanks so much for the feedback”

Maybe it’s for the best 🤷🏻‍♂️

I have no clue to be honest. In any caee, it seems that I’ve been blocked and can no longer reply. Have you been blocked, too? Did this person block ALL cryptographers?

Well, instead of blocking me, you could have added me to the list instead 🤣

Is this… is this… a list of cybersecurity experts without a single cryptographer 😰?

Here is a list of amazing (applied) crypto folks I found here:

I’d also be interested in this one. Are you recording/streaming it by any chance?
