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

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.
