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

Yay! Added a link in the repo (plus links to all the other frameworks and most of their docs).

.@marcella_h_'s talk at #realworldcrypto 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: mp-spdz.readthedocs.io/en/latest/

"The paper 'SoK: General Purpose Compilers for Secure Multi-Party Computation' is highly recommended for those who are interested in finding the right MPC framework to choose for their real world secure computational needs" @aysajanabidin reports from #realworldcrypto

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!! github.com/multiparty/jiff #realworldcrypto

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! acrab.org #RealWorldCrypto

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 @marcella_h_ 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. twitter.com/JoshuaWBaron/s…

A Dutch bank recently used it to implement a page rank algorithm in transaction graphs for fraud detection!

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 @hicsail are presenting a JIFF tutorial at #IEEESecDev 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 @shaananc wrote about how inadequate threat modeling can lead to practical attacks--in this case on a NIST-standardized random number generator. @penndsl
