摘要
研究和解决数据隐私保护问题对无线传感器网络的大规模应用具有重要意义,同时无线传感器网络的特征使得数据隐私保护技术面临严重挑战.目前无线传感器网络数据隐私保护技术已成为研究热点,主要针对数据聚集、数据查询和访问控制中数据隐私保护问题进行了研究.文中对无线传感器网络数据隐私保护现有研究成果进行了总结,从数据操作任务和隐私保护实现技术两个维度对现有研究成果进行了分类,介绍了网络模型、攻击模型和安全目标,阐述了代表性协议的关键实现技术,分析和比较了代表性协议的性能并总结了各协议的主要优缺点,最后指出了未来的研究方向.
Data privacy preservation is essential to widespread deployment of wireless sensor networks. However, the characteristics of wireless sensor networks make it face serious challenges. Data privacy preservation techniques in wireless sensor networks have attracted more and more attentions, and its research is mainly concentrated on data privacy preservation solutions for data aggregation, data query and access control in wireless sensor networks. This paper surveys the state of the art of data privacy preservation techniques in wireless sensor networks. Existing research results are classified according to two dimensions which are data manipulation tasks and privacy-preserving techniques. This paper introduces the network model, the attack model and security goal of each type of protocols, describes the key techniques of the important protocols, analyzes and compares the performance of these protocols, and summarizes the main advantages and disadvantages of these protocols. At last, suggestions for future research works are put forward.
