摘要: 随着数据隐私保护需求的日益增长,联邦学习凭借其无需共享原始数据即可实现联合模型训练的特性,已成为保护数据隐私的重要方法。然而,联邦学习在实际应用中仍面临诸多挑战,如恶意客户端的投毒攻击、通信成本高以及中心服务器计算负载过重等问题。为此,提出了端-边-云协同的联邦学习框架,通过分层管理客户端、边缘服务器和云服务器,有效降低云服务器的通信负担,提高系统的扩展性和效率。同时,在该框架下设计了结合基于声誉评估的局部模型聚合与基于全同态加密的全局模型聚合的联邦学习算法,以有效应对数据投毒攻击。实验结果表明,端-边-云协同的联邦学习框架不仅增强了系统对恶意攻击的防御能力,还有效降低了通信开销并提升了系统效率。

Abstract: With the increasing demand for data privacy protection, federated learning has emerged as a crucial method for safeguarding data privacy due to its ability to enable joint model training without sharing raw data. However, federated learning still faces numerous challenges in practical applications, such as poisoning attacks by malicious clients, high communication costs, and excessive computational load on central servers. To address these issues, a federated learning framework with end-edge-cloud collaboration is proposed. By hierarchically managing clients, edge servers, and cloud servers, this framework effectively reduces the communication burden on cloud servers while improving system scalability and efficiency. Additionally, a federated learning algorithm was designed
within this framework, combining reputation-based local model aggregation and fully homomorphic encryption-based global model ag⁃
gregation to effectively counteract data poisoning attacks. Experimental results demonstrate that the federated learning framework with end-edge-cloud collaboration not only enhances the system's defense against malicious attacks but also significantly reduces communication overhead and improves system efficiency.
