针对两层无线传感器网络中范围查询所要求的低能耗和高隐私保护,提出了一种具有隐私和完整性保护的安全范围查询协议SPQ(secure probabilistic range query)。SPQ是由数据加密、前缀成员验证、概率邻居验证、查询传输过程分离等技术组成,能够在保证不泄露隐私的情况下完成范围查询。分析和仿真结果表明,相对于其他安全协议,SPQ在保证范围查询安全性的同时具有更低能耗。
For the requirement of low power consumption and high privacy-preserving in two-tiered wireless sensor networks,this paper proposed a secure range query protocol with privacy and integrity protection called SPQ( secure probabilistic range query). SPQ consists of data encryption,prefix membership verification,probabilistic neighborhoods verification,and the separation technology of query and transmission process. It could ensure to complete range queries without privacy reveal. Analyses and simulation results show that,it compared to other security protocols that SPQ can guarantee the security of range query,and at the time it has the lower power consumption.
