摘要:

在随机网络中,隐私保护的数据聚合是一个具有挑战性的问题,考虑到分布式通信和控制需求、动态网络拓扑和不可靠通信链路等。与广泛使用的加密方法不同,本文通过利用分布式共识技术解决这一挑战。我们首先提出了一种安全共识基于数据聚合(SCDA)算法,该算法在保证准确汇总的同时保护敏感数据的隐私。然后,我们证明所提出的算法能够准确收敛,并且是(ε,σ)-数据隐私,提供了ε和σ之间的数学关系。大量仿真显示,所提出的算法具有高准确性和低复杂性,并且对网络动态具有鲁棒性。

英文摘要:

Privacy-preserving data aggregation in ad hoc networks is a challenging problem, considering the distributed communication and control requirement, dynamic network topology, unreliable communication links, etc. Different from the widely used cryptographic approaches, in this paper, we address this challenging problem by exploiting the distributed consensus technique. We first propose a secure consensus-based data aggregation (SCDA) algorithm that guarantees an accurate sum aggregation while preserving the privacy of sensitive data. Then, we prove that the proposed algorithm converges accurately and is $(ε, σ)$-data-privacy, and the mathematical relationship between $ε$ and $σ$ is provided. Extensive simulations have shown that the proposed algorithm has high accuracy and low complexity, and they are robust against network dynamics.
