OpenHuFu

OpenHuFu is a multi party computation framework used for data query benchmarks. It provides flexibility for researchers to quickly implement their algorithms, such as secret sharing, garbled circuit and oblivious transfer. With its help, we can quickly take the experiment and get the performance of our algorithms.

Building OpenHuFu from Source

prerequisites:

• Linux
• Java 11
• Maven (version at least 3.5.2)

Run the following commands

git clone https://github.com/BUAA-BDA/OpenHuFu.git
cd OpenHuFu
./build/script/package.sh

OpenHuFu is now installed in release
