面向WSN的安全范围查询协议研究

Research of secure range query protocol for wireless sensor networks

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。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 low power consumption and high privacy protection required for range query in two-tiered wireless sensor net-works,a secure range query protocol with privacy and integrity protection called SPQ （Secure probabilistic range query） is pro-posed. SPQ consists of data encryption,prefix membership verification,probabilistic neighborhoods verification,and separation technology of query and transmission process. It can ensure the achievement of range query without privacy reveal. Analyses and simulation results show that SPQ has the lower power consumption relative to other security protocols under the precondition to guarantee the security of range query.
