Abstract: IEEE 802.16 is the standard for broadband wireless access. The security sublayer is provided within IEEE 802.16 MAC layer for privacy and access control, in which the privacy and key management (PKM) protocols are specified. In IEEE 802.16e, SA-TEK 3-way handshake is added into PKM protocols, aiming to facilitate reauthentication and key distribution. This paper analyzes the SA-TEK 3-way handshake protocol, and proposes an optimized version. We also use CasperFDR, a popular formal analysis tool, to verify our analysis. Moreover, we model various simplified versions to find the functions of those elements in the protocol, and correct some misunderstandings in related works using other formal analysis tools.

摘要: IEEE 802.16是无线宽带接入的标准。在IEEE 802.16 MAC层内有一个安全子层,用于隐私保护和访问控制,其中定义了一个隐私和密钥管理(PKM)协议。在IEEE 802.16e新标准中,SA-TEK 3步握手协议被添加到PKM协议里,旨在方便重新认证和密钥分发。本文分析了SA-TEK 3步握手协议,指出了它的缺陷,并提出了一个优化版本。我们还使用了流行的形式化分析工具CasperFDR来验证我们的分析。我们对该协议的各种简化版本进行了建模,以确定协议中相关元素的功能。此外我们还比较了其它形式化工具比如Scyther的分析结果,并纠正了相关工作中的一些错误。非形式化分析和形式化分析的结果都验证了我们改进的协议更加高效可靠,而Casper工具在分析特定安全属性方面也具有一定的优势。
