| 摘 要： | 隐私性与完整性是无线传感器网络(WSN)数据融合中的两大难题。在低能耗隐私保护(ESPART)算法的基础上,提出了一种新的保护隐私性与完整性的数据融合(iESPART)算法。它通过加入同态消息验证码机制,在不改变隐私性的前提下,实现了完整性保护。同时,利用消息验证码在融合时密钥改变的特性, iESPART能够判断遭到攻击的具体节点位置。仿真实验结果表明,相比完整性保护(iPDA)算法,该算法具有相同的隐私保护性与更全面的完整性检测机制,花费的通信开销更少。

| Abstract: | How to protect data privacy and data integrity is the major challenge in data aggregation of Wireless Sensor Networks (WSN). This paper proposed an integrity-Energy-Saving Privacy-preserving Aggregation (iESPART), which was based on Energy-Saving Privacy-preserving Aggregation (ESPART). By using a homomorphic message authentication code scheme, iESPART was not only able to protect data integrity, but also able to determine which nodes had been attacked. The simulation results show that iESPART achieves the same data privacy-preserving effect as integrity-protecting Private Data Aggregation (iPDA), with a more comprehensive integrity detection mechanism and less communication overhead. |
