FedDefender: Client-Side Attack-Tolerant Federated Learning. (arXiv:2307.09048v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Federated learning enables learning from decentralized data sources without
compromising privacy, which makes it a crucial technique. However, it is
vulnerable to model poisoning attacks, where malicious clients interfere with
the training process. Previous defense mechanisms have focused on the
server-side by using careful model aggregation, but this may not be effective
when the data is not identically distributed or when attackers can access the
information of benign clients. In this paper, we propose a new defense
mechanism that focuses …
