A Scalable Encryption Routing Protocol for Privacy Preserving on Sensor Networks

为了解决无线传感器网络中传统的数据隐私保护技术在抵御网络外部攻击或内部攻击以及数据隐私窃取等方面所存在的数据投递率低、网络稳定性差等缺陷,提出一种动态数据聚合加密的数据隐私保护路由算法,通过使用复数的加法法则进行可扩展数据聚合以及分段密钥等方法来实现对数据隐私的保护。仿真实验结果表明,所提路由算法具有数据投递率高、安全性高和网络稳定性较强等优点,能极大增强无线传感器网络防御典型数据隐私攻击的能力。

In order to solve the problem of low data delivery rate and poor network stability in traditional data privacy protection mechanisms which is against external and internal network attacks and data stealing on wireless sensor networks,this paper proposes a dynamic data aggregation and encryption routing protocol for privacy preserving on wireless sensor networks. The data privacy preserving is achieved by using the method of data aggregation and hierarchically encryption algorithm. The simulation results show that the proposed routing protocol has high data deliver rate,high network security,strong stability and extensibility in aspect of solving data privacy attacks. It enhanced the ability to against typical data privacy attack greatly.
