中文摘要：

文章在基于装有Open Wrt和Click的无线路由器所搭建的无线mesh网络测试床上，研究使用Click模块化路由编程工具，结合802．11i和802．11s草案针对无线mesh网络安全的协议设计方案，提出在无认证服务器环境中，使用预共享密钥进行数据包链路层加密以确保mesh节点间通信保密可靠的安全解决方案。

英文摘要：

On the test-bed of wireless mesh network based on the wireless router with OpenWrt and Click, a design of security mechanism is proposeed to present the privacy and integrity between mesh access points with pre-shared keys used for encryption of data packets in link layer in the environment without authenticator servers, according to 802. 11i and 802.11 s protocols and studying of Click modular router.
