传感器网络数据汇聚是减少冗余传输,降低能耗的主要手段.文章提出了一种高效的传感器网络加密数据汇聚方案,汇聚节点在无需明文的情况下完成数据完整性检查、身份认证、数据比较等,保证了端到端数据安全传输.与相关数据汇聚方案相比,除了具有较高的安全性,本文方案较好地利用了邻居节点数据冗余度高的特点,进一步降低了通信开销.
Data aggregation in a wireless sensor network is an important method to reduce redundant transmission and energy consumption. Authors propose an efficient encrypted data aggregating method for wireless sensor networks, the aggregators complete the data integrity checking, source identity authentication and data aggregation without a plaintext and provide the end-to-end security for data transmission. Compared with related schemes, besides higher security, the proposed scheme makes better utilization of high redundancy of neighbor sensors' readings and reduces the communication overhead effectively.
