Secure-innerproduct

C++ implementation of computing inner product between a server's bit vector and a client's bit vector based on additively homomorphic encryption

Installation Requirements

Create a working directory (e.g., work) and clone the following repositories.

   mkdir work
   cd work
   git clone git://github.com/cBioLab/secure-innerproduct.git
   git clone git://github.com/herumi/xbyak.git
   git clone git://github.com/aistcrypt/Lifted-ElGamal.git
   git clone git://github.com/herumi/mie.git
   git clone git://github.com/herumi/cybozulib.git
   git clone git://github.com/herumi/cybozulib_ext.git

• Xbyak is a prerequisite for optimizing the operations in the finite field on Intel CPUs.
• OpenSSL and libgmp-dev are available via apt-get (or other similar commands).

Installation

  cd secure-innerproduct
  mkdir bin comm
  cd src
  make

• Before compiling inner_client.cpp, please replace "localhost" of the following line by your server's hostname.

std::string hostname = "localhost";

• use tcmalloc (optimal) for Linux; sudo apt-get install libgoogle-perftools-dev

Usage

server side:
cd secure-innerproduct
mkdir comm/server
cd bin
inner_server "database_file"

client side:
cd secure-innerproduct
mkdir comm/client
cd bin
inner_client "query_file"

File format

Prerequisite Files and Libraries for Running Your Application

* OpenSSL
* GMP (libgmp-dev)
