Very interesting talk when it comes to the SotA of Quantum Computing: www.youtube.com/watch?v=OkVY...

Great to see some progress towards a Two-Round ECDSA Threshold Signature Scheme: eprint.iacr.org/2025/1696

This is an interesting paper that allows for a context to be added to Threshold Decryptions: eprint.iacr.org/2025/279

Excited to share my implementation of the paper "Verifiable Timed Signatures Made Practical" by Thyagarajan et al. More specifically I implemented the Verifiable Timed Commitment scheme described in section E.

This is a really interesting FHE paper in which BGV is used to build an ALU to do arithmetic as well as logical operations on messages in Z_2^n (e.g. 64 bit machine words). eprint.iacr.org/2025/1449

Currently deep down the rabbit hole to finish my implementation of "Verifiable Timed Signatures Made Practical" eprint.iacr.org/2020/1563 While doing so I had to update my LHTLP implementation. It now features a range proof and new homomorphic operations: github.com/primefactor-...

ZKSecurity just dropped this truly awesome PlonK tutorial: plonk.zksecurity.xyz

This is an interesting read on how EdDSA's hash-based key derivation (RFC 8032) can be used to compute PQ-ZKPs for private key ownership proofs: eprint.iacr.org/2025/1368 This is good news as it allows for an easier transition towards Post Quantum secure cryptocurrencies.

Ingonyama just published the first three lessons of their "Foundations of High-Speed Cryptography" course 👀 www.ingonyama.com/foundations-...

This paper looks really interesting: eprint.iacr.org/2025/770 ZKPs for (F)HE Schemes based on Ring-LWE. FHE + ZKPs are a dream combo.

The recording of the Diamond iO talk by the Machina iO team that was held during the Simon Institute's "Obfuscation" workshop was just uploaded: www.youtube.com/watch?v=1RcK...

This is a great paper that explains how to obtain indistinguishability obfuscation (iO) via recursive Functional Encryption: piazza.com/class_profil... It's basically a simplified version of the [BV15] paper: eprint.iacr.org/2015/163

The Machina iO Team just published a blog post which serves as a great introduction to indistinguishability obfuscation (iO): machina-io.com/posts/unboxi...

Interesting read about Google’s recent "longfellow-zk" implementation: news.dyne.org/longfellow-z...

What a great episode with the legend Ralph Merkle. I came for the Cryptography and stayed for the insights into Cryonics and general life lessons. www.youtube.com/watch?v=90py... As I wrote before, the Podcast by @billatnapier.bsky.social is an absolute gem if you're interested in Cryptography.

Turns out there's currently an ongoing "Obfuscation" Workshop / Symposia hosted by the Simons Institute! simons.berkeley.edu/workshops/ob... They just uploaded the "Expedition to Obfustopia" video by Rachel Lin which IMHO is the best overview of the SoTA of iO: www.youtube.com/watch?v=2PRU...

Got a first e2e implementation of a WebGPU Compute Shader up and running. It's written in Zig and uses WebGPU via the Dawn project so I can run it on my MacBook's M1 GPU.

Been working hard to make my MacBook's M1 GPU Go Brr and run NTT on it. ~200 lines of Zig later and I got most of the basic plumbing done. Not sure if the headache comes from my new glasses or the WebGPU API 😅

For anyone interested in learning more about Indistinguishability Obfuscation (iO) I highly recommend watching this talk by Amit Sahai: mediaspace.illinois.edu/media/t/1_ur... I scoured the internet for a good introduction to the topic and this is the best talk so far IMHO.

Nice website that lists MPC Deployments alongside a short writeup and additional resources to dive deeper into the respective deployment: mpc.cs.berkeley.edu

Just optimized the NTT / FFT implementation and removed the allocator so that ZERO heap allocations are now performed. This works because the degree of the cyclotomic polynomial / FFT vector length is a parameter (denoted as n) that's agreed upon in advance (i.e. not dynamic).

Good overview with real-world uses of Differential Privacy: desfontain.es/blog/real-wo... The same author also wrote a nice intro to Differential Privacy: desfontain.es/blog/friendl...

Excited to dive into this new iO paper. Another interesting construction is "Diamond iO" from the PSE Team: eprint.iacr.org/2025/236

Really important effort. Consider donating or becoming a member if you care about privacy and the future of the internet in general.

Been studying GPU architectures recently and man, this video is absolute gold: youtube.com/watch?v=h9Z4... The channel in general has stunning animations and explainers on various topics.

Been studying FFT and NTT a lot recently for my GPU optimized NTT implementation as well as in preparation to implement the CKKS FHE scheme. After reading tons of resources I have to say that this writeup from Jeff Erickson finally made FFTs click for me: jeffe.cs.illinois.edu/teaching/alg...

Nice website with a list of Privacy Enhancing Technology (PET) Use Cases. The list can be filtered by attributes such as sector, stage of development or technology used (e.g. HE, MPC, DP, etc.). cdeiuk.github.io/pets-adoptio...

Now that the math behind (i)NTT and FFTs in general is covered it's time to implement it.

Currently working my way through FFTs and (i)NTT specifically. One of the best resources I've found so far is this paper: eprint.iacr.org/2024/585.pdf It has a few typos, but if you follow along with pen and paper you should grok NTT without much pain.

The "sss" repository includes an implementation of Shamir's Secret Sharing.

The "lindell17" repository contains a full implementation of the paper "Fast Secure Two-Party ECDSA Signing" by Yehuda Lindell.

The "paillier" repository includes an implementation of the Paillier Cryptosystem by Pascal Paillier. In addition to encryption and decryption, you'll also find code for homomorphic operations that can be computed over ciphertexts.

The second repository is called "lhtlp" and contains an implementation of the paper "Homomorphic Time-Lock Puzzles and Applications" by Malavolta et al.

The first project I'd like to share is the "ecc" repository which contains various primitives used for Elliptic Curve Cryptography.

Excited to announce Primefactor! Primefactor is a Research and Development Lab that explores the forefront of cryptographic advancements.

This is a really good article on FHE which highlights what kind of abstractions (the "FHE Stack") are necessary to streamline FHE engineering. cacm.acm.org/research/unl...

Sunscreen just open sourced their Parasol Processor which is a virtual processor that runs computations over encrypted data using their own variant of TFHE: github.com/Sunscreen-te...

The Distributed Lab team just published their "ZKDL Lecture Notes": zkdl-camp.github.io/files/summar... It comes with many examples and is a great resource to learn more about the state-of-the-art in Zero Knowledge Cryptography.

Really good overview of recent developments in Lattice-based ZKPs: zkv.xyz/lattice-base... There's also a new episode on the Zero Knowledge Podcast with Vadim Lyubashevsky which covers Lattice-based ZK Systems: zeroknowledge.fm/podcast/359/

For those who enjoyed reading "Constant-Time Code: The Pessimist Case" by Thomas Pornin (2025/435), here's what I would consider "The Optimist Case": eprint.iacr.org/2025/759 Joint work with Santiago Arranz-Olmos, Gilles Barthe, Benjamin Grégoire, Jan Jancar, Vincent Laporte, and Tiago Oliveira.

Apparently the scheme that’s used is based on this paper: eprint.iacr.org/2024/2010 Here’s a nice presentation that explains how it works: youtube.com/watch?v=dlO9...

Good paper that explores optimizations and trade-offs for polynomial multiplication via NTT with a focus on Lattice-based Cryptography: eprint.iacr.org/2025/768

It’s awesome to see big tech giants adopting these kind of cutting edge privacy technologies. First FHE, now ZKPs.

Haven't watched it yet, but Tim Sweeney interviews are always full of nuggets, so I'll definitely give this a watch / listen: www.youtube.com/watch?v=477q... Another good one is the interview with John Carmack: www.youtube.com/watch?v=I845...

FHE + ZKPs is the dream combo as you want to be sure that the outsourced computation was carried out correctly. This new paper looks into new ZKP constructions to prove that a RLWE-based FHE computation (i.e. BGV / CKKS) was done correctly: eprint.iacr.org/2025/770

Great explanation of Quantum Computing and Grover's Algorithm!

Awesome to see new research on practical indistinguishability obfuscation. The PSE Team implemented their lattice-based "Diamond iO" scheme that is proven secure under the LWE assumption. Blog Post: machina-io.com/posts/hello_... Paper: eprint.iacr.org/2025/236 Code: github.com/MachinaIO/di...

Interesting talk by Nadim Kobeissi on his team's most recent Coinbase CB-MPC Cryptography audit: www.youtube.com/watch?v=2wR2... The audit report can be found here: cure53.de/audit-report... And here's a link to the GitHub repo: github.com/coinbase/cb-...
