无线传感器网络中节能与隐私保护范围查询

针对无线传感器网络中范围查询高隐私性与低能耗的要求，提出了一种节能的安全范围查询处理算法EPRN。EPRN对数据查询过程与上传过程进行分离，避免了所有节点将自身感知数据传输至存储节点或基站，大大降低了网络传输过程通信量，延长了网络寿命。运用前缀成员验证、数据加密等技术对感知数据以及查询范围进行处理，从而达到隐私保护的目的。理论分析和仿真实验显示，EPRN在保证数据隐私性的同时具有更好的节能性。

Energy- Saving and Privacy-Preserving Range Query in Wireless Sensor Networks

For the requirement of high privacy-preserving and energy-saving in wireless sensor networks, this paper proposed a secure range query algorithm with low power consumption called EPRN(Energy-Saving and Privacy-Preserving Range Query in Wireless Sensor Networks).EPRN separates query process form transmission process, which can avoid all nodes sending their whole data to storage nodes or sink, greatly reduce the traffic in the process of network transmission and prolong the network lifespan, at the same time, sensory data and query range are proceed with the technologies of data encryption and prefix membership verification ,which could ensure the security of data. Analyses and simulation results show that EPRN has the lower power consumption on the premise of protecting data privacy.
