Neil Gong, "Secure Federated Learning"

Federated learning is an emerging machine learning paradigm to enable many clients (e.g., smartphones, IoT devices, and edge devices) to collaboratively learn a model, with help of a server, without sharing their raw local data. Due to its communication efficiency and potential promise of protecting private or proprietary user data, and in light of emerging privacy regulations such as GDPR, federated learning has become a central playground for innovation.  However, due to its distributed nature, federated learning is vulnerable to malicious clients.  In this talk, we will discuss local model poisoning attacks to federated learning, in which malicious clients send carefully crafted local models or their updates to the server to corrupt the global model. Moreover, we will discuss our work on building federated learning methods that are secure against a bounded number of malicious clients.
