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 is an important branch of modern communication system and is an important technical support for ubiquitous communication. However, a large number of network attacks lead to data security threats, seriously affecting network reliability, so that the value of wireless sensor networks is greatly reduced. Aiming at the security of wireless sensor network, a LCTR model of low-energy tree routing protocol based on energy-efficient and energy-efficient is proposed. The model uses message authentication code and digital signature technology to achieve authentication and data integration. The performance of LCTR model is analyzed by using common message authentication code and digital signature technology. The simulation results show that the success rate of information security transmission in LCTR model can be increased by up to 23% and the network lifetime can be increased up to 5%.
