Decor

Decor framework for evaluating non-linear functions in Secure Multiparty Computation.

Installation

Note: Decor runs only on Linux at the moment.

Install Decor by running a following set of commands:

mkdir -p $HOME/.codon && curl -L https://github.com/exaloop/codon/releases/download/v0.17.0/codon-$(uname -s | awk '{print tolower($0)}')-$(uname -m).tar.gz | tar zxvf - -C $HOME/.codon --strip-components=1 && \
curl -L https://github.com/0xTCG/sequre/releases/download/v0.0.20-alpha/sequre-$(uname -s | awk '{print tolower($0)}')-$(uname -m).tar.gz | tar zxvf - -C $HOME/.codon/lib/codon/plugins && \
git clone -b decor-patch-64 --depth 1 https://github.com/0xTCG/sequre.git .sequre && \
cp -r .sequre/stdlib/ $HOME/.codon/lib/codon/plugins/sequre/ && \
alias decor="find . -name 'sock.*' -exec rm {} \; && CODON_DEBUG=lt $HOME/.codon/bin/codon run --disable-opt="core-pythonic-list-addition-opt" -plugin $HOME/.codon/lib/codon/plugins/sequre"

And then export GMP library to Decor like so (either custom or the one provided at external/GMP/lib/libgmp.so)

export SEQURE_GMP_PATH=external/GMP/lib/libgmp.so

Run

Navigate to the root of this directory and run all essential experiments by executing tests.sequre

decor -release tests.sequre --skip-mhe-setup --use-ring --local

Inspect the results by running all cells in provided plots.ipynb notebook.

Troubleshooting

In some cases Decor might be unable to link a Python library. Make sure to export CODON_PATH in that case to the location of your libpython.so. For example:

export CODON_PYTHON=$HOME/miniconda3/lib/libpython3.13.so
