Abstract: IEEE802.16 Standard as the advanced wireless air interface technology also faces the inherent security problem of wireless network, especially in its unclearly defined Mesh network architecture. This article will focus on the other supported mesh mode to continue the the security problem. After analysis the scheme for MESH mode, an improved security scheme to resolve security problem in existed standard will be proposed.

摘要： IEEE802.16标准（WiMAX）作为一种先进的无线空中接口技术，同样面临着不可规避的无线网络安全问题。在其定义的两种网络模式——PMP模式和MESH模式，特别是在其没有完全定义的MESH网络结构中存在着安全问题。这篇文章将针对该标准定义除PMP模式外的另一种网络结构MESH模式下的安全机制进行分析和研究。通过对MESH模式下的安全分析，本文对原有的安全机制进行了改进。
