FLPhish: Reputation-based Phishing Byzantine Defense in Ensemble Federated Learning

The increasing demand for privacy protection facilitates growing interests in Federated Learning (FL). Nevertheless, most of existing FL schemes are susceptible to malicious participating clients compromised by Byzantine attacks, which remains a challenging issue. In this paper, we propose a novel Byzantine-robust FL scheme, coined FLPhish. Specifically, we first design a ensemble learning-based F...
