摘　　要：无线传感网中安全数据查询技术的研究已引起了广泛的关注,其中以存储节点为中间层的两层传感器网络中安全Top-k查询技术的研究具有重要的现实意义。现有的安全Top-k查询技术主要针对查询过程中数据的隐私保护和查询结果的完整性验证等问题开展研究工作。从安全性能和通信性能两个维度出发对现有的两层传感器网络中的安全Top-k查询技术进行了总结,介绍了网络模型查询模型,以及查询过程中存在的安全性问题;同时分析和总结了现有的各协议所采用的关键技术以及其主要优点和不足,最后指出了未来可能的研究方向。The research of secure data query in wireless sensor networks has attracted more and more attentions, and it is important to research secure Top-k query in two-tiered wireless sensor networks, in which storage nodes is intermedia- te layer of networks. The present research about secure Top-k queries in two-tiered sensor networks is mainly concen- trated on solutions of data privacy preservation and query result verification. This paper surveyed the current state of the art of secure Top-k query techniques in two-tiered sensor network according to two dimensions, which are security and communication performance, and introduced the network model, query model and security questions in query process. This paper summarized the key techniques of current protocols and the main advantages and disadvantages of these protocols. At last, this paper pointed out possible research direction in the future.
