摘要
如何保护隐私信息在无线传感器网络的应用过程中不被泄露,同时能得到较为准确的结果,是无线传感器网络面临的重大挑战。近年来国内外学者对无线传感器网络的隐私保护技术进行了很多研究,本文从位置隐私保护和数据隐私保护两方面,总结了现有的隐私保护方法,分析了其基本原理和特点。针对现有方法的不足,本文提出了一种能同时保护位置隐私和数据隐私的隐私保护方法,该方法基于多节点幻影路由技术和椭圆曲线同态加密技术。与现有技术相比,该方法具有更好的隐私保护性和更低的能量消耗性。
A great challenge to wireless sensor network （WSN） is how to protect privacy from disclosing during application in WSN as well as obtain accurate results. In recent years, researchers at home and abroad have done much work on privacy preserving in WSN. This paper surveyed the general privacy preserving methods from two aspects of location privacy and data privacy in WSN and analyzed their theories and characteristics. A new method based on multi-notes phantom routing protocols and ECC homomorphic encryption was proposed, which could protect location privacy and data privacy at the same time. Compared to current methods, better privacy will be protected and less energy will be consumed.
