中文摘要：
无线传感器网络节点不仅有信息感知和数据通信的能力，还需兼备路由器的功能，研究其路由安全对增大网络强壮性有着重要意义。在介绍无线传感器网络特点及路由技术要求的基础上，分析其路由面临的安全威胁，针对不同威胁描述了密钥管理技术和安全路由协议等相应的安全方案，通过对现有安全方案的分析，提出了几种研究安全路由技术的方法。
英文摘要：
The nodes of wireless sensor networks contain not only the capacity of information sensing and digital communication, but the function of router as well. It is greatly important to research on the routing security for the increase of the robustness of the network. Based on the survey of features and technical requirements of wireless sensor networks, this paper analyzes the threats faced by routing security. According to different threats it also describes security schemes in key management techniques and secure routing protocols. Finally, it provides some ideas on researching secure routing techniques through the analysis of the existing security schemes.
