Principal Cheese Researcher at Microsoft Research. I tweet about cheese, and occasionally formal verification, cryptography (HACL*/EverCrypt), type systems, etc
Seattle, WA
Joined September 2010
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).

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

I recently wrote about ongoing efforts to retarget the compilation of HACL* from C to Rust. Today, Aymeric, myself and the entire HACL* team are happy to announce that we have a first alpha release...

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

Just made the repository public:

Eurydice compiles (a modest subset of) Rust to C. Verify programs in Rust, still get C code for legacy environments. - AeneasVerif/eurydice

Over the past few years, a lot of eyes in the software verification community have turned towards Rust. That’s hardly a surprise: programs written in Rust are easier to verify, owing to the languag...

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

Had a great time doing a keynote at @ProssimoISRG on Microsoft approach to memory safety. Made a huge announcement - @microsoft is going big on Rust and spending $10 million to make it 1st class language in our engineering systems + $1 million @rustlang foundation.
HUGE move for security at Microsoft. Lets' go!!!!

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! https://t.co/o2fJhTOMld

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👇 https://t.co/vp1sX81tJ7

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

Data formats used for cryptographic inputs have historically been the source of many attacks on cryptographic protocols, but their security guarantees remain poorly studied. One reason is that, due...

My student Théophile is being modest. Our paper (with Karthik and Benjamin) *also* got a distinguished paper award! Congrats Théophile !
I am glad to announce that my very first paper received the Internet Defense Prize at @USENIXSecurity ! https://t.co/GW67ZsOo2Q

While I was presenting remotely, I think my short talk on @BlawxAI was well-received, and I look forward to engaging with the participants going forward. Huge thanks to @DMerigoux and @_protz_ and @basus for chairing. May your success continue for many years to come. 8/

#ProLaLa2023 is done and was a big success! Thanks to lots of hard work from @DMerigoux and @_protz_ and our session chairs. Lots of great research, conversations and future work to be done. My little nerd heart is so, so happy right now.
