| 摘 要： | 无线传感器网络中隐私保护技术已经成为研究热点,其中隐私保护精确Skyline查询协议已成为富有挑战性的研究问题.提出一种两层传感器网络隐私保护Skyline查询协议(PPSQ).该协议通过采用Z-O编码技术并结合HMAC机制,使得存储节点可以在无需感知数据明文的情况下判断出元组的支配关系,从而得出密文查询结果,保护了数据的隐私安全性;并通过辅助计算节点计算的验证码来保证查询结果的完整性.理论分析和实验结果表明,PPSQ协议能够保证感知数据、查询结果的隐私安全性和查询结果的完整性,且性能优于现有工作.

| Abstract: | Privacy preservation has attracted more and more attentions in wireless sensor networks. It is a challenge to provide precise Skyline query result while preserving data privacy in wireless sensor networks. This paper proposes a privacy-preserving Skyline query protocol in two-tiered sensor networks (PPSQ). Using Z-O encoding and hash-based message authentication code mechanism, this protocol to allows storage node to attain tuple relations of domination judgment without the sensory data plaintext, and therefore protects privacy of sensory data. In addition, assisted computing node calculates the verification code to ensure the integrity of the query result. Theoretical analysis and experimental results show that the PPSQ can guarantee the privacy of sensory data and the integrity of query result, and it also has better performance than the previous work in skyline query processing. |
