This paper proposes a blockchain-based Federated Learning (FL) framework with
Intel Software Guard Extension (SGX)-based Trusted Execution Environment (TEE)
to securely aggregate local models in Industrial Internet-of-Things (IIoTs). In
FL, local models can be tampered with by attackers. Hence, a global model
generated from the tampered local models can be erroneous. Therefore, the
proposed framework leverages a blockchain network for secure model aggregation.
Each blockchain node hosts an SGX-enabled processor that securely performs the
FL-based aggregation tasks to generate a …
