Sanitizer: Blazing-Fast, Private, and Robust Federated Learning

Sanitizer is a new framework for federated learning (a training method where multiple computers learn together without sharing raw data) that addresses two major challenges: privacy and Byzantine attacks (when some computers send bad or malicious data). The framework uses more efficient cryptographic techniques and two new protocols for combining data from multiple sources, achieving 19-23 times faster performance than existing methods while maintaining accuracy and security.
