PQ-MPC

This repository contains the code for the paper "Secure Two-Party Computation in a Quantum World" by Niklas Büscher, Daniel Demmler, Nikolaos P. Karvelas, Stefan Katzenbeisser, Juliane Krämer, Deevashwer Rathee, Thomas Schneider, and Patrick Struck, which will appear at ACNS'20.

Required packages:

• libgmp-dev
• SEAL (version 3.1.0)

Compilation

To compile the library:

mkdir build && cd build
cmake ..
make
// or make -j 4 for faster compilation

Tests

To compile the tests, run cmake -DBUILD_TESTS=ON .. && make in build/. Then run the test binaries in build/bin/ as follows to make sure everything works as intended:

./<test> 1 <port> [circuit] [iterations] & ./<test> 2 <port> [circuit] [iterations]
