两层无线传感器网络中存储节点负责存储传感节点的数据和处理Sink节点的查询请求.然而,由于存储节点的重要性,使得存储节点成为攻击者攻击的目标,特别是存储节点被攻击者捕获后,攻击者能够获取隐秘的传感数据、伪造传感数据和丢弃部分查询结果等.因此,提出了一种安全的范围查询方案,保证了数据的机密性和真实性,并利用签名融合技术,极大地降低了通信量,且具有较高的完整性检测概率.在此基础上,提出了一种检测率更高的范围查询方案.理论分析和实验结果显示,所提出的方案具有较高的检测率和较低的通信量.
The storage nodes in WSNs are responsible for storing the data of sensing nodes and querying Sink nodes, however, the storage nodes become the targets of attacker’s attacks due to the importance of storage nodes, especially the storage nodes are captured by the attacker , The attacker can obtain the hidden sensing data, fake the sensing data and discard some of the query results, etc. Therefore, a secure range query scheme is proposed to ensure the confidentiality and authenticity of the data, and the signature fusion technology , Greatly reducing the traffic, and has a high probability of integrity detection.On the basis of this, a higher detection rate range query program is proposed.The theoretical analysis and experimental results show that the proposed scheme has a higher The detection rate and lower traffic.
