FL-OA: A Byzantine-Robust Federated Learning Framework with Outsourced Auditing for Intelligent Devices

Hongliang Zhang, Zhongyuan Yu, Fenghua Xu +3

Federated learning (FL) enables multiple intelligent devices to collaboratively train a high-accuracy model without sharing raw data. However, due to its distributed nature, FL is…

Defending Against Backdoor Attacks via Alignment Checking in Model-Contrastive Federated Learning

Hongliang Zhang, Zhongyuan Yu, Guijuan Wang +4

The paper proposes FedDAB, a two‑phase defense for federated learning that uses contrastive regularization and alignment checking to detect and exclude malicious local updates caus…

Local Distance Query with Differential Privacy

Weihong Sheng, Jiajun Chen, Bin Cai +3

Differential Privacy (DP) is commonly employed to safeguard graph analysis or publishing. Distance, a critical factor in graph analysis, is typically handled using curator DP, wher…
