Kick Bad Guys Out! Zero-Knowledge-Proof-Based Anomaly Detection in Federated Learning. (arXiv:2310.04055v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Federated learning (FL) systems are vulnerable to malicious clients that
submit poisoned local models to achieve their adversarial goals, such as
preventing the convergence of the global model or inducing the global model to
misclassify some data. Many existing defense mechanisms are impractical in
real-world FL systems, as they require prior knowledge of the number of
malicious clients or rely on re-weighting or modifying submissions. This is
because adversaries typically do not announce their intentions before
attacking, and re-weighting might …
