Building and running Secrecy

Repository organization

This repository is organized as follows:

The deployment folder contains automation scripts to deploy secrecy in AWS in either same region or cross region setups.
The src folder contains the core functionality of Secrecy, including the implementation of MPC primitives, relational oblivious operators, and party communication.
The examples folder contains the implementation of example queries with the Secrecy API.
The src/test folder contains various unit and end-to-end tests.
The src/experiments folder contains the implementation of various microbenchmarks and performance experiments.
Plotting scripts and other helper utilies are located in the results/scripts folder.

Dependencies

To build Secrecy, you will need to install:

CMake
Libsodium
an MPI implementation, such as OpenMPI or MPICH.
Create a new directory include/external-lib and clone https://github.com/mfaisal97/sql-parser inside it.

Building and running using the `CMakeLists.txt` file:

Make sure you have pkg-config installed.

On Linux:

sudo apt install pkg-config

On OSX:

brew install pkg-config

To compile and run all test cases:
```
./run_tests.sh
```

To run a specific test file or experiment:

First use cmake to create the build dir and make file:
```
mkdir build
cd build
cmake ..
```

Build and run a test file:

cd build
make planner
mpirun -np 3 ./planner ../examples/queries/q1.txt ../examples/schemas/q1_schema.txt 128 128  // Will compile and run Q1 with 128 and 128 rows per input tables
