🎉 I am now a Research Scientist at Web3 Foundation! Looking forward to working with jeffburdges, Alistair Stewart, Chen-Da Liu-Zhang, Alfonso Cevallos, Sergey Vasilyev, and the rest of the team!

I am truly grateful to have received the Best Early Career Paper Award at CRYPTO for “Fully Adaptive Schnorr Threshold Signatures” with Chelsea Komlo and Mary Maller. Thank you to the Chairs, Britta Hale, @annalysyanskaya, and Helena Handschuh and PC for this tremendous honour!!

IMA International Conference on Cryptography and Coding (IMACC23) deadline is July 12 - submit your papers on foundational theory/mathematics, cryptography/coding results and implementations. ima.org.uk/21435/19th-ima…

Really happy to have received news yesterday that myself, Elizabeth Crites, and Mary Maller won the Best Early Career Paper Award at Crypto 2023 for our paper “Fully Adaptive Schnorr Threshold Signatures” eprint.iacr.org/2023/445 💪💃😊

Also, our Real World Crypto talk on multi-party Schnorr signatures (in theory and practice) can be found here: youtube.com/watch?v=-d0Ny7…. It was a pleasure sharing the stage with Tim Ruffing and Chelsea Komlo.

Thank you, Crossfyre 2024, for the opportunity to share some of my research interests in such a fun and welcoming environment. I’ve uploaded my slides here: elizabeth-crites.github.io/activities.html

My London Crypto Day slides are available here: elizabeth-crites.github.io/activities.html. Thank you, Nick Spooner, Martin R. Albrecht, Sarah Meiklejohn, Liz Quaglia, and Al Cutter for inviting me!

Structure-preserving signatures are used for anonymous credentials, anonymous e-cash, blind signatures, and more. We introduce the first *threshold* SPS, which is fully non-interactive. Joint work with markulf kohlweiss, Bart Preneel, Mahdi Sedaghat, Daniel Slamanig. eprint.iacr.org/2022/839

Check out my talk with Chelsea Komlo at #Zcon3 on new research on FROST and optimized FROST2. Thank you Zcash Foundation 🛡️ for hosting me! Video here: youtube.com/watch?v=cAfTTf…

Looking forward to reading the work on Practical Delegatable Creds! Among other things, we implemented the mercurial signature by Elizabeth Crites Anna Lysyanskaya using the BLS12-381 in RUST obtaining nice running times too, confirming that these constructions are practical!
