摘　　要：现有传感器网络聚集查询隐私保护方法采用加解密的形式保护节点感知数据,且需要网络中的所有节点参与查询处理。过多加解密操作会大量消耗节点能量,且用户可能只对其中部分区域的聚集结果感兴趣。针对这些问题,提出一种抗窃听攻击的传感器网络空间范围聚集查询处理算法PCPDA。该算法沿着既定路线,一边查询一边聚集,使得算法不依赖于预先构造好的拓扑结构,适用于网络拓扑结构动态变化的传感器网络,节省了维护拓扑结构的开销。该算法在未采用任何加密措施情况下保证了节点感知数据的隐私性。理论分析和仿真结果表明,PCPDA在能量损耗和隐私保护方面都优于现有算法。Currently,in sensor networks,the privacy-preserving aggregation query processing methods use the form of encryption and decryption to protect sensing data,and require all nodes in the network to participate in query processing.Excessive encryption and decryption operations consume a lot of node energy,and users may be only interested in the aggregate result of the partial region.To deal with these problems,a sensor network spatial range aggregation query processing algorithm against eavesdropping attacks(PCPDA:Part of the area based on cluster Privacy-preserving Data Aggregation)is proposed.The algorithm gathers along the established route while querying,so that the algorithm does not depend on the pre-configured topology and is suitable for the sensor network with dynamically changed network topology,which saves the overhead of maintaining the topology.The algorithm guarantees the privacy of node-aware data without any encryption measures.Theoretical analysis and simulation results show that PCPDA is superior to the existing algorithms in terms of energy loss and privacy protection.
