Implementation of the system described in this paper

Remark This is an implementation of the proceedings version of the paper, that has a bug in the way constant values are handled. The current eprint version of the paper corrects this. This will be fixed in the next release of this prototype.

Prerequisites

• A Unix-like environment (e.g., Linux, mingw-w64)
• GCC compiler, GMP development libraries
• CodeBlocks IDE (optional, for re-building on Windows)
• Python 2.7 with Twisted and GMPY

For instance, on Amazon Linux the following commands install the required dependencies:

sudo yum install gcc-c++ gmp-devel
pip install --upgrade pip
sudm pip install twisted gmpy scipy

Installation instructions

• After cloning the repository, download the dependencies:

git submodule init
git submodule update

• Compile the ate-pairing library with SNARK support:

cd ate-pairing
make SUPPORT_SNARK=1

• On Unix, compile the C++ library and tools by running run make from the main directory

• On Windows (64-bits), binaries are included so building is not necessary; to re-build, open qaps.workspace in CodeBlocks and choosing "Rebuild Workspace" (also works on Unix)

• Install our customized VIFF version:

cd tueviff-fp-inlinecb
python setup.py install

Running examples

• For generic examples, see simple.py, simple2.py, and simple3.py in the viff directory. Edit and run test.sh from the bin directory to run these examples
• For the "aggregate" and "logrank" examples from the paper, edit and run test_anon.sh and test_stat.sh, respectively
