Our work on multi-message multi-recipient public key encryption is out! We build on Kyber (ML-KEM) and get great efficiency. Kudos to Hongxiao Wang for leading this work!

Mad at Meta? Don't Let Them Collect and Monetize Your Personal Data If you’re fed up with Meta right now, you’re not alone. Meta tracks you across millions of websites and apps and its business model relies on your data. If you want to limit Meta’s ability to collect ...

The wonderful @eff.org has an equally wonderful guide you can use to make it MUCH harder for Meta / Facebook / Instagram to collect and monetize your personal data. It's not super easy - offer to do this for family & neighbors who might not be able to: www.eff.org/deeplinks/20...

Congratulations to @erkantairi.bsky.social , former PhD student in the Security and Privacy Group at TU Wien, on his FWF Schrödinger fellowship, which will allow him to spend 2 years at UC Berkeley and then 1 year at IST Austria. I am very proud of you and all the best for the future!

UK Crypto Day: 20 February 2025 Schedule

Khanh and Eamonn are organising UK Crypto Day on 20 February at King's College London.

Registration is free (and open) but required: uk-crypto-day.github.io/2025/02/20/u...

Help us spread the word and see you there.

In real-life applications, each key share typically is held by a different entity and become its key. So compromising an entity’s key does not compromise the secret message

To add, there is also an approach called Threshold Cryptography where the main secret key is split into multiple “shares” and comprising one key share basically does not help. Access to sufficiently many key shares is needed to infer something meaningful (like recovering the message)

This is a significant result if correct in my view. I didn’t check the technical details yet, but they get Dilithium-like signature but with about 3x reduction in signature size; almost as compact as Falcon.

Apparently one does not need to fly very long to do this..

A “heuristic” proof? What does that mean???

Where do we email to have our competitors’ papers rejected for publication? :)

Not sure about QR-code bills, but here in Australia I believe most people just set up direct debit where the biller is automatically paid from the customer’s bank card/account (after initial authorisation). Very convenient imo
