Happy new year.
While 2026 is an rsa modulus, it is not a product of Sophie Germain primes so it's probably a bad idea to use it.

My colleagues from Cybernetica and I decided to make another variant of Smart-ID / SplitKey protocol. Coppercloud is a two-party blind RSA signing with private key being split between a user and a server.
Perfect for the future of privacy-preserving digital wallets! 🌐✨

New paper written with my colleagues Jelizaveta Vakarjuk and Peeter Laud from Cybernetica just got accepted to ProvSec2025 πŸ₯³

In this paper, we aim to combine server-supported signatures together with fail-stop properties.

P.S. yes, protocol’s name is inspired by Mistborn series

I suggest looking at TOPCOAT (link.springer.com/article/10.1...) since DiLizium is an outdated pre-print

Thrilled to share a new paper written with my colleagues -- Trilithium (Star Trek reference is intended).

Our protocol is secure in UC model and allows two parties to construct FIPS compliant quantum-safe signature!

Also, explaining public-key cryptography to the first-year student is much more convenient using RSA and/or pure DH than EC primitives or Crystals-Kyber.

I understand for some (maybe many) universities/countries it makes sense, but not in Estonia. The most popular authentication solution, Smart-ID is based on threshold RSA. We still support RSA in our encryption standard - www.id.ee/en/article/c...

So I will be teaching RSA for quite some time

We are now more than 30 years into the quantum computing hype. https://dl.acm.org/doi/pdf/10.1145/190616.190617 OMG it's the end of cryptography! zzz😴

Very excited to share our first exploration of threshold MAYO (yes, the PQC algorithm)! πŸŽ‰ Joint work with the amazing
Daniel Escudero and Guilhem Niot. The ideas can extend to UOV as wellβ€”let’s have MV-based threshold cryptography!

Though, to be honest, Twitter had nice ePrint updates until API got broken 😬

I don't know what impresses me more - BlueSky having ePrint updates or ePrint Updated Bot being able to find my profile and tag it 🀨

Thank you, @muzosh.bsky.social for implementation and bringing this code to life! Let us hope there will be many other PQ schemes we will work together in the future.

The implementation for the TOPCOAT (link.springer.com/article/10.1...) is now public!!! Check it out at - github.com/ISRI-PQC/top...
