    Abstract:

    As data silos emerge and importance is attached to personal privacy protection, the application modes of centralized learning are restricted, whereas federated learning has attracted great attention since it appeared owing to the fact that it, as a distributed machine learning framework, can accomplish model training without leaking users’ data. As federated learning is increasingly widely applied, its security and privacy protection capability have also begun to be questioned. This study offers a systematic summary and analysis of the research achievements domestic and foreign researchers have made in recent years in the security and privacy of federated learning models. Specifically, this study outlines the background of federated learning, clarifies its definition and workflow, and analyzes its vulnerabilities. Then, the security threats and privacy risks against federated learning are systematically analyzed and compared respectively, and the existing defense methods are summarized. Finally, the prospects of this research area and the challenges ahead are presented.
