deki-smpc-server

deki-smpc-server is the server-side component of the deki-smpc ecosystem, enabling Secure Multi-Party Computation (SMPC) for federated learning.
It includes the Key Aggregation Server and the FL Aggregation Server, all deployable effortlessly with Docker Compose.

🛠️ Components

• Key Aggregation Server
  REST API (FastAPI) for efficient, concurrent multi-party key generation and secure key exchange.
• FL Aggregation Server
  Secure federated model aggregation based on FastAPI and PyTorch. (Used to be Flower)
• Redis
  In-memory store for temporary key material and synchronization between parties.

🚀 Quickstart

1. Clone the repository:

   git clone https://github.com/your-org/deki-smpc-server.git
   cd deki-smpc-server

2. Launch the servers with Docker Compose:

   docker-compose up --build

✅ This will start:

• Key Aggregation Server at http://localhost:8080
• Redis Server at localhost:6379

⚙️ Configuration

The following environment variables are used (with their default values):

Variable	Description	Default
HOST	Host IP to bind to	0.0.0.0
NUM_CLIENTS	Number of expected clients	10
EPOCHS	Number of training epochs	1
PORT	Port to serve on	8080
PRESHARED_SECRET	Secret key used for secure communication	my_secure_presHared_secret_123!
REDIS_HOST	Redis host	redis
REDIS_PORT	Redis port	6379

You can override any of these by editing the docker-compose.yml file.

⚠️ Work in Progress

This is currently a work in progress to transfer the implementation used for the experiments in the paper into a clean and fully usable implementation.
