A C++ implementation of labeled Private Set Intersection from Distributed Point Function.

Vcpkg is a helpful package manager for C and C++. If you've never used vcpkg before, or if you're trying to figure out how to use vcpkg, check out their Getting Started section for how to start using vcpkg. Employing vcpkg, we install the dependencies for our DPFPSI by the following commands.

vcpkg install kuku
vcpkg install openssl
vcpkg install ms-gsl
vcpkg install boost-system 
vcpkg install boost-regex

git clone --recursive https://github.com/lqvir/DPFPSI.git
mkdir build 
cd build 
cmake .. -DCMAKE_TOOLCHAIN_FILE=/your/path
cmake --build . 

We invoke the Garble Circuit based OPRF in mobile_psi_cpp including an old version librelic which may fail to build by the error in 'mobile_psi_cpp/droidCrypto/relic/src/md/blake.h'. We can handle this error as follows:

// Update the line 64 in obile_psi_cpp/droidCrypto/relic/src/md/blake.h 
// ALIGNME( 64 ) typedef struct __blake2s_state
typedef struct __blake2s_state

// Update the line 89 in obile_psi_cpp/droidCrypto/relic/src/md/blake.h 
// ALIGNME( 64 ) typedef struct __blake2b_state
typedef struct __blake2b_state
