A Privacy Protection Scheme for Federated Learning Based on RSA Homomorphic Encryption
针对现有联邦学习安全聚合方案存在梯度信息泄露、参与方计算开销较大以及缺乏对模型的完整性保护等问题,文中提出一种基于RSA(Rivest-Shamir-Adleman)同态加密的联邦学习隐私保护方案.采用构建高效且安全的RSA同态加密算法解决梯度数据泄露问题,利用中央服务器实现解密计算以降低参与方的计算开销.基于区块链的不可篡改性、存证保护等特性将数据训练过程中关键数据进行上链存证,实现对模型数据的全生命周期维护.通过安全性分析可知,所提方案具有抗合谋攻击以及密文不可区分性.由性能以及效率方面分析对比结果可知,所提方案较传统方案具有一定优势.
In view of the problems of the current federated learning security aggregation schemes,such as gradi-ent information leakage,large computational overhead of the participants,and lack of integrity protection for the mod-el,this study proposes a federated learning privacy protection scheme based on RSA(Rivest-Shamir-Adleman)ho-momorphic encryption.The problem of gradient data leakage is solved by constructing an efficient and secure RSA homomorphic encryption algorithm,and the decryption calculation is implemented through the central server to reduce the computational overhead of the participants.Based on the immutability and evidence preservation protection fea-tures of blockchain,the key data during the data training process is stored on the chain for evidence preservation,a-chieving the full life cycle maintenance of model data.Through security analysis,it can be known that the proposed scheme has the ability to resist collusion attacks and the indistinguishability of ciphertexts.Through the analysis and comparison in terms of performance and efficiency,it can be known that the proposed scheme has certain advantages over the traditional scheme.
