由于没有物理边界，无线网络面临的安全威胁比有线网络多得多。因此，在IEEE 802.16标准中，在MAC层中指定了安全子层以解决固定宽带无线接入（BWA）上的隐私问题。在IEEE 802.16-2001标准发布后，已经发表了几篇文章来解决IEEE 802.16安全性中的缺陷。然而，IEEE标准802.16-2004修订版并没有解决所有发现的问题，仍然存在其他缺陷。本文对IEEE 802.16标准进行了概述，重点介绍了MAC层，特别是安全子层。我们分析了标准中的安全缺陷以及在相关的作品，并说明了可能的攻击的认证和密钥管理协议。还提出了防止这些攻击的可能解决方案。最后，我们提出了一个安全切换协议，应支持在未来的802.16e的移动性。
Without physical boundaries, a wireless network faces many more security threats than a wired network does. Therefore, in the IEEE 802.16 standard a security sublayer is specified in the MAC layer to address the privacy issues across the fixed Broadband Wireless Access (BWA). Several articles have been published to address the flaws in IEEE 802.16 security after the IEEE standard 802.16-2001 was released. However, the IEEE standard 802.16-2004 revision does not settle all the discovered problems and additional flaws remain. This paper gives an overview of the IEEE 802.16 standard, focusing on the MAC layer and especially the security sublayer. We analyze the security flaws in the standard as well as in related works, and illustrate possible attacks to the authentication and key management protocols. Possible solutions are also proposed to prevent these attacks. Finally, we propose a security handover protocol that should be supported in the future 802.16e for mobility.
