Non-interactive and Output Expressive Private Comparison from Homomorphic Encryption

This repo includes the implementation of our paper Non-interactive and Output Expressive Private Comparison from Homomorphic Encryption

Requirements

• Boost
• NTL

Build

1. Setup NTL_HEADER and NTL_LIB in the main CMakeLists.txt file.
2. Clone the submodule by git submodule init & git submodule update
3. Make the build directory mkdir build
4. Run cmake inside the build director cmake -DCMAKE_BUILD_TYPE=Release .. & make

RUN

1. For playing the server's role, ./main r=1 i=<tree model file>
2. For playing the client's role, ./main r=0 i=<client input file>

There are some samples in the samples directory.

CONFIG

• We can run the decision tree evaluation with both encrypted tree model and encrypted client's input. To do so, turns the macos PLAIN_THRESHOLD to 0 in files PPDTClient.cpp and PPDTServer.cpp.

• Modify the port number and ip address in main.cpp.
