Secure Join implements oblivious two party database joins on secret shared table. It include the permutation protocols of iacr/2024/547 and the Alternating Moduli secret shared PRF protocols of iacr/2024/582.
The library can be cloned and built with networking support as
git clone https://github.com/Visa-Research/secure-join.git
cd SecureJoin
python3 build.py
The output library secure-join and executable frontend will be written to out/build/<platform>/. The frontend can perform PSI based on files as input sets and communicate via sockets. See the output of frontend for details.
The library and any fetched dependancies can be installed.
python3 build.py --install
or
python3 build.py --install=install/prefix/path
if a custom install prefix is perfered. Install can also be performed via cmake.
By default the depenancies are fetched automaticly. This can be turned off by using cmake directly or adding -D FETCH_AUTO=OFF. For other options see the cmake output or that of python build.py --help.
If the dependancie is installed to the system, then cmake should automaticly find it. If they are installed to a specific location, then you call tell cmake about them as
python3 build.py -D CMAKE_PREFIX_PATH=install/prefix/path
