摘要:

物联网设备正在迅速扩展并产生大量数据。越来越需要探索从这些设备收集的数据。协作学习为物联网环境提供了战略解决方案,但也引起了公众对数据隐私的担忧。近年来,基于安全多方计算和差分隐私的隐私保护技术得到了大量的发展。协作学习的一个主要挑战是在保持高计算效率的同时平衡泄露风险和数据效用。本文提出了一种基于矩阵加密的隐私保护逻辑回归模型。该方案能够抵抗选择明文攻击、已知明文攻击和合谋攻击,从而使协作学习中的任何机构都能受到攻击。加密的模型估计被解密以提供真实的模型结果而不降低精度。验证阶段的实施是为了检查代理机构之间的不诚实行为。实验结果表明,该算法具有快速收敛和高效性。

英文摘要:

Internet of Things devices are expanding rapidly and generating huge amount of data. There is an increasing need to explore data collected from these devices. Collaborative learning provides a strategic solution for the Internet of Things settings but also raises public concern over data privacy. In recent years, large amount of privacy preserving techniques have been developed based on secure multi-party computation and differential privacy. A major challenge of collaborative learning is to balance disclosure risk and data utility while maintaining high computation efficiency. In this paper, we proposed privacy preserving logistic regression model using matrix encryption approach. The secure scheme is resilient to chosen plaintext attack, known plaintext attack, and collusion attack that could compromise any agencies in the collaborative learning. Encrypted model estimate is decrypted to provide true model results with no accuracy degradation. Verification phase is implemented to examine dishonest behavior among agencies. Experimental evaluations demonstrate fast convergence rate and high efficiency of proposed scheme.
