To run the scripts, you only need a recent version of Python and MPyC installed.
Ciphers can be run directly. Appending -M n will run the script with n parties:
python3 chacha20bin.py -M 3
The operations.py script will run benchmarks of basic operations and output csv-files.
To run the scripts, you need MP-SPDZ installed; especially, you need to make shamir-party.x.
You can either copy the scripts to Programs/Source in your MP-SPDZ directory, then compile them like this:
./compile.py lowmc
And then run them like this:
Scripts/shamir.sh lowmc
Or you can follow the instructions here.
