针对无线传感器网络中数据的范围查询所要求的低能耗和高隐私保护要求,提出一种能保护数据的隐私性和验证数据的完整性的低能耗范围查询协议(SPRQ).基于两层传感器网络,SPRQ协议采用质数融合技术来保护所查询数据的隐私性;同时,SPRQ基于和值链的验证方案,将传感器节点采集的感知数据构成一条隐形的数据链,Sink节点通过验证数据链的完整性以实现对查询结果的完整性的判断.通过理论分析,说明了SPRQ可保证查询过程中数据的安全性;仿真实验结果表明,SPRQ所采用的质数融合技术能够有效地减少前缀编码过程中所增加的数据量,使得无线传感器网络中节点的能耗更低.
Aiming at the requirements of low power consumption and high privacy protection required by the range query of data in wireless sensor networks, a Low Energy Range Query Protocol (SPRQ) that can protect the privacy of data and verify the integrity of data is proposed. Based on the two-layer sensor network , The SPRQ protocol uses the technique of prime number fusion to protect the privacy of the queried data. At the same time, based on the verification scheme of the sum chain, the SPRQ perceives data collected by the sensor nodes as an invisible data link. The Sink node verifies the integrity of the data link So as to realize the judgment of the integrity of the query result.According to the theoretical analysis, it is proved that SPRQ can ensure the data security in the query process. The simulation results show that the SPRQ fusion algorithm can effectively reduce the increase of prefix coding The amount of data, making wireless sensor network node energy consumption lower.
