ABSTRACT = {With the increasing complexity of malware attack techniques, traditional detection methods face significant challenges, such as privacy preservation, data heterogeneity, and lacking category information. To address these issues, we propose Federated Dynamic Prototype Learning (FedDPL) for malware classification by integrating Federated Learning with a specifically designed <i>K</i>-means. Under the Federated Learning framework, model training occurs locally without data sharing, effectively protecting user data privacy and preventing the leakage of sensitive information. Furthermore, to tackle the challenges of data heterogeneity and the lack of category information, FedDPL introduces a dynamic prototype learning mechanism, which adaptively adjusts the clustering prototypes in terms of position and number. Thus, the dependency on predefined category numbers in typical <i>K</i>-means and its variants can be significantly reduced, resulting in improved clustering performance. Theoretically, it provides a more accurate detection of malicious behavior. Experimental results confirm that FedDPL excels in handling malware classification tasks, demonstrating superior accuracy, robustness, and privacy protection.},
