无线传感器网络低能耗树状路由安全性能

Low-energy consumption tree routing security for wireless sensor networks

安全可靠的无线传感器网络是现代通信系统的重要分支,是面向泛在通信的重要技术支撑。然而,大量的网络攻击导致数据安全受到威胁,严重影响网络可靠性,从而使无线传感器网络的使用价值大大降低。针对无线传感器网络的安全性问题,提出了以高效节能为前提的低能耗树状路由协议的安全模型LCTR模型。该模型利用报文鉴别码和数字签名技术实现鉴权和数据整合。通过采用常用报文鉴别码和数字签名技术作为参考对LCTR模型进行性能分析,仿真结果表明,LCTR模型下信息安全传输成功率最多可提高23%,网络生存时间最多可提高5%。

Safe and reliable wireless sensor network （WSN） is an important branch of modern communication systems, and is an important technical support for ubiquitous communication. However, a large number of network attacks will threaten data security, which will seriously affect network reliability and greatly reduce the use value of WSN. This paper proposes a security model for lowenergy consumption tree routing protocols （LCTR）, which achieves authentication and data integration using message authentication code （MAC） and digital signature （DS） techniques. Some common MACs and DSs have been taken as the reference to analyze the performance of LCTR. Simulating results show that with the model of LCTR, the safe transmitting rate of information is increased by 23% at most, and the network lifetime is increased by 5% at most.
