Attacks

This example demonstrates how to inject an attack during FL training. We utilize logistic regression, MNIST dataset, and the optimizer FedAVG. The source code locates at https://github.com/FedML-AI/FedML/tree/master/python/examples/federate/security/mqtt_s3_fedavg_attack_mnist_lr_example. We provide sample configurations for byzantine attacks (zero/random/flip mode), label flipping attack, and model replacement attack at https://github.com/FedML-AI/FedML/tree/master/python/examples/federate/security/mqtt_s3_fedavg_attack_mnist_lr_example/config. As an example, we utilize byzantine attack of random mode and set the number of FL clients to be 4.

If you have multiple nodes, you should run the client script on each node

APIs

The highly encapsulated server and client API calls are shown as below. Note that we set the path of the configuration file in the two bash scripts to be config/byzantine/fedml_config.yaml to load the configuration for byzantine attack.

run_server.sh is as follows:

#!/usr/bin/env bash

RUN_ID=$1
python3 torch_server.py --cf config/byzantine/fedml_config.yaml --rank 0 --role server --run_id $RUN_ID

torch_server.py

import fedml
from fedml import FedMLRunner

if __name__ == "__main__":
args = fedml.init()

# init device
device = fedml.device.get_device(args)

# load data
dataset, output_dim = fedml.data.load(args)

# load model
model = fedml.model.create(args, output_dim)

# start training
fedml_runner = FedMLRunner(args, device, dataset, model)
fedml_runner.run()

run_client.sh

#!/usr/bin/env bash
RANK=$1
RUN_ID=$2
python3 torch_client.py --cf config/byzantine/fedml_config.yaml --rank $RANK --role client --run_id $RUN_ID

torch_client.py

import fedml
from fedml import FedMLRunner

if __name__ == "__main__":
args = fedml.init()

# init device
device = fedml.device.get_device(args)

# load data
dataset, output_dim = fedml.data.load(args)

# load model
model = fedml.model.create(args, output_dim)

# start training
fedml_runner = FedMLRunner(args, device, dataset, model)
fedml_runner.run()

At the client side, the client ID (a.k.a rank) starts from 1. Please also modify fedml_config.yaml, changing the client_num_in_total the as the number of clients you plan to run.

At the server side, run the following script:

bash run_server.sh a

For client 1, run the following script:

bash run_client.sh 1 a

For client 2, run the following script:

bash run_client.sh 2 a

For client 3, run the following script:

bash run_client.sh 3 a

For client 4, run the following script:

bash run_client.sh 4 a
