    Our paper "SoK: General Purpose Compilers for Secure Multi-Party Computation" was accepted to IEEE S&P 2019 and is now available online!

    Now that is out, I am looking for a summer internship 😇. I am interested in Security and Systems. I have done mostly speculative execution attacks so far (but not only). Please contact me if you are looking for interns 😀

    .'s talk at reminded me that more documentation should be my resolution for 2020, so here's a first slice on the core high-level functionality of MP-SPDZ:

    As mentioned by Kinan Dak Albab, JIFF is a new general-purpose MPC framework for web-based applications! It’s highly customizable with a focus on usability. Tutorials and docs available. Look out for the paper & v1 release this February!!

    We put together a site to look for applied crypto research. Eprint is great, but wading through 1500 papers/yr for 100 practical papers is 💩. Join us and help out!

    The problem with MPC is that it's often very difficult to setup! You might even need to compile custom OpenSSL versions 😅 Thankfully the authors have a set of Docker containers to spare us the time on their github!

    The work of on the usability of multi-party computation came at a good time, creating this survey. Some research efforts do need to be timed correctly to make a real impact.

    First up is Marcella Hastings from UPenn and of course we are starting with Danish sugar beet auctions 🤣

    New twitter handle. Sadly is still taken, but this will do for now.

    Check out JIFF if you want to deploy MPC for people who can't download software. Full disclosure: I worked with this team over the summer. They are great and JIFF is flexible and cool and used for real applications! They even have a test suite

    The folks at are presenting a JIFF tutorial at tomorrow. It'll cover basics on MPC and an end-to-end deployment--in just 90 minutes!

    I added JIFF to the MPC frameworks repository last week. JIFF is a Javascript implementation of secure multiparty computation in the semi-honest model. It hooks up to the browser, which makes it super easy for end users.

    Happily, patching is in progress for several vendors! But this is a tricky side channel that could have been avoided with more careful modeling

    My labmate wrote about how inadequate threat modeling can lead to practical attacks--in this case on a NIST-standardized random number generator.

    It's me! Chugging away on efficient preprocessing algorithms for JIFF

    So while you'd be hard-pressed to find an area of computer science research that doesn't have code quality issues, academic MPC tools are way more likely to be used tomorrow than, say, the average experimental kernel.
