Principal Cheese Researcher at Microsoft Research. I tweet about cheese, and occasionally formal verification, cryptography (HACL*/EverCrypt), type systems, etc

We have more post-docs in Azure Research! Consider applying to in Systems & Security (https://t.co/zLQ1ile0Np) or in AI Security & Privacy (https://t.co/1VU8SFgtu2).

Quick reminder that I'm co-chairing VSTTE with @AzaleaRaad this year, and submission deadline is in just a few days!! https://t.co/6U3Cp6u3XU

@djco *clone

[Jonathan Protzenko @_protz_]

HACL*, the verified crypto library, now available as pure, safe Rust: https://t.co/RhVJXAaa6c -- alpha release.

[Jonathan Protzenko @_protz_]

@djco For now, you can close the repository and directly use the package here: https://t.co/Na9tqp9Rrb relying on path dependencies in your cargo file: https://t.co/8pvc3zKAl5

[Jonathan Protzenko @_protz_]

@djco This will eventually be distributed as part of libcrux which I believe will have all of the bells and whistles like proper packaging and documentation.

@BRIAN_____ @cryptopathe I think that’s one of the conclusions of the Kyber experiment by @_franziskus_ and Goutam. Most of it is pure state-passing yet ends up delivering the same performance anyhow.

[Jonathan Protzenko @_protz_]

New blog post! I share plans to modernize HACL* by bringing it to a pure, safe Rust world. I also talk about a new backwards-compat tool, Eurydice, for new verified Rust code that still needs to exist in legacy C environments. https://t.co/l1m8DKQUrk

[Jonathan Protzenko @_protz_]

@BRIAN_____ @cryptopathe Yes we need something general because sometimes indices are indeed non constant but still relatable to each other, e.g. f() and f()+4

[Jonathan Protzenko @_protz_]

@BRIAN_____ @cryptopathe Yes we haven’t observed anything meaningful in terms of perf. Even cases where it got faster (perhaps because the callee is a local function and never receives aliased arguments anymore).

@lastland0 Please get in touch with @sonmarcho and I!

[Denis Merigoux @DMerigoux]

Another amazing endeavour of nimble compilation to connect proofs, programs and languages together, by my esteemed PhD advisor!

[Jonathan Protzenko @_protz_]

Just made the repository public: https://t.co/U8DIWHENCZ

It was an absolute pleasure to be here and I had a blast! Thanks for the invitation, it was an honor to be in such great company.

[Ilya Sergey @ilyasergey]

Super excited to have @_protz_ visiting @NUSComputing and giving an invited talk on formally verified cryptography and security protocols!

[Formal Ferris @FormalFerris]

here we go! This month we will meet one week early on Jan. 22 to hear @_protz_ talk about HACL-Rust and Eurydice. Make sure to join us!

[Son Ho @sonmarcho]

I was very happy to give a talk at Galois to present the latest progress on Aeneas, our framework to verify Rust programs. On the menu: latest features, future extensions, ongoing verification effort, and most of all demo of the Lean backend!

Our quantum-resistant protocol upgrade, PQXDH, is now “the first machine-checked post-quantum security proof of a real-world cryptographic protocol.”

Thanks to the researchers who did this important formal verification! Read more from them here👇

A new paper called "Comparse: Provably Secure Formats for Cryptographic Protocols" is out! https://t.co/YZ61SriwJe
A few explanations below. 🧵
