Trident Installation¶

Trident contains multiple applications: PIR, LR_TRAIN, KNN, PSI and Framingham Heart Study.

Step 1: Install poseidon¶

Please install the poseidon library before use it. poseidon is divided into two versions Install Software Library, Install Hardware Library, poseidon with HPU version requires a corresponding hardware acceleration card, and it is generally recommended to install the normal version.

Step 2: Install dependencies¶

Cmake Variables¶

Apps in Trident are independent and depend on Poseidon and cmake provides an option for each application to compile or not. As follows:

CMake Variable	Type	Usage	Default
PIR	bool	Build PIR	ON
LR_TRAIN	bool	Build LR_TRAIN	ON
HEARTSTUDY	bool	Build HEARTSTUDY	ON
KNN	bool	Build KNN	ON
APSI	bool	Build APSI	ON

Only APSI needs to install dependencies. If you don't compile apsi, you can skip this step and use cmake .. -DAPSI=OFF when generating makefile.

# install flatbuffers
sudo apt install libflatbuffers-dev
# install json
sudo apt install libjsoncpp-dev
# install log4
sudo apt install liblog4cplus-dev

Step 3: Compile Trident¶

# download the source code, use http or ssh
git clone https://github.com/luhang-HPU/Trident.git #http
git clone git@github.com:luhang-HPU/Trident.git #ssh

# go to the folder
cd Trident
# create a compilation directory
mkdir -p build && cd build

# compile
cmake ..
make -j
