Byzantine Attack

Byzantine attacks target distributed systems, such as federated learning and decentralized consensus algorithms, by introducing malicious or faulty nodes that disrupt the computation or communication process. Current research focuses on developing robust aggregation rules and algorithms, often employing techniques like geometric median, trimmed mean, and median-of-means, to mitigate the impact of these attacks, even under data heterogeneity and non-IID settings. Understanding and addressing Byzantine robustness is crucial for ensuring the reliability and security of distributed machine learning and other decentralized applications, impacting the trustworthiness of models trained in these environments. The development of Byzantine-resilient algorithms is a significant area of ongoing research, with a focus on improving both theoretical guarantees and practical performance.
