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

Prerequistes:

• 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

Hu-Fu is now installed in release
