中文摘要： 针对无线传感器网络节点位置信息的安全需求，以安全测距为基础，节点安全定位和源位置隐私保护为目标，构建层次化传感器网络位置信息的安全体系结构。在测距信号层，采用信号处理方法研究适合传感器网络的RSSI抗干扰方法和抗攻击理论，解决RSSI值易受攻击和环境干扰等难点问题；在此基础上，设计安全、稳定、精确的RSSI测距协议。在定位层，分别研究面向粗精度测距的可验证定位算法、确定性的分布式节点位置校验机制和恶意信标节点检测机制，实现节点定位安全；在位置隐私方面，分别基于位置感知和分簇策略，研究面向局部流量分析攻击的分散性幻象路由算法和面向全局流量分析攻击的可扩展数据查询协议。通过本项目的研究，实现对传感器网络节点位置信息安全的综合保障，为传感器网络节点位置信息安全体系的建立提供理论和技术支持。

英文摘要： This project is focused on the design of a secure hierarchical architecture to accommodate the security requirements of node position in wireless sensor networks(WSNs). The proposal is based on secure ranging, with the aim to providing secure node positioning and source-location privacy protection. In ranging layer, the anti-jamming and attack-resistant technique for RSSI，which are suitable for WSNs，are studied based on digital signal processing method. Based On those technologies, a refined RSS-based ranging protocol is proposed to realize attack-tolerant and reduce errors. In positioning layer,a suite of distributed techniques are described to secure node localization, including coarse-ranging based verifiable multilateration, deterministic location verification and detection of malicious beacon node. By applying location-aware and clusering method in networks layer, a dispersive phantom routing protocol secure against local eavesdropper and a privacy-preserving data querying protocol secure against global eavesdropper are respectively proposed to preserve the location privacy of source sensors. We believe this project will provide not only an overall protection for position information in WSNs, but also the theoretical and technological support for building its security architecture.
