Where to Look for Frameworks • Very many MPC Frameworks are out there • MPC Framework So. K [HHNZ]: – https: //github. com/MPC-So. K/frameworks – Many frameworks available as Docker containers • Outside of So. K Repository: – Sharemind (https: //sharemind. cyber. ee/sharemind-mpc/) – MPy. C(https: //github. com/lschoe/mpyc) MPC Frameworks - 2 ABY 02/26/20

How to Choose a Framework 1. How many parties – 2 or more 2. What threat model – semi-honest or malicious 3. Model of Computation - Boolean, Arithmetic, or Mixed 4. Programming language - C/C++, Java, Python, Special purpose 5. Available operations – Arrays, comparison, fixed point, etc. 6. Level of access – just want to use existing ops, or want to modify ops - this also applies to some degree to level of measurement 7. Usability / Difficulty to build – Marcella’s framework takes away some of this work MPC Frameworks - 16 ABY 02/26/20

Recommendations • High Level – Sharemind – Scale Mamba • Lower Level – MPy. C – EMP-Toolkit (if only need Boolean computation) – ABY MPC Frameworks - 17 ABY 02/26/20
