摘要

摘要: 该文针对无线传感器网络(WSNs)数据聚合与安全目标之间的矛盾，基于隐私同态和聚合消息验证码技术提出一种同时保障数据隐私性与完整性的可恢复数据聚合方案。该方案支持由聚合结果恢复出各感知数据，从而一方面能够验证感知数据和聚合数据的完整性，另一方面能够对原始数据进行任意所需的处理，不受聚合函数类型的限制。安全分析表明该方案不仅支持数据隐私性、完整性，还能够抵抗未授权聚合攻击，聚合节点俘获攻击，且能够在一定范围内检测及定位恶意节点。性能分析表明，该方案相比其他算法在通信和计算开销方面具有显著优势。为了评估方案性能和可行性，基于TinyOS给出了算法的原型实现。实验结果表明，该方案开销较低，对于资源受限的WSNs是高效可行的。

Abstract: To address the contradiction between data aggregation and data security in Wireless Sensor Networks (WSNs), a recoverable privacy-preserving integrity-assured data aggregation scheme is proposed based on the technologies of privacy homomorphism and aggregate message authentication code. The proposed scheme enables the Base Station (BS) to recover all the original sensing data from the final aggregated results, which makes it possible to verify the integrity of each sensing data and aggregated data, and perform any further operations on them on demand. The security analysis shows that the proposal not only provides the data privacy and data integrity, but also resists against unauthorized aggregation attack and aggregator capture attack; besides, it is able to detect and locate the malicious nodes which injects false data to the network in a certain range. The performance analysis shows that the proposed scheme has remarkable advantages over existing schemes in terms of computation and communication overhead. In order to evaluate the performance and feasibility of the proposal, the prototype implementation is presented based on the TinyOS platform. The experiment results demonstrate the proposed scheme is feasible and efficient for resource-constrained WSNs.
