IEEE 802.16安全机制的研究与实现

Research and Implementation of IEEE 802.16 Security Mechanism

分析并讨论了IEEE 802.16标准的安全机制,指出了其安全缺陷和最新标准的相关安全改进工作。在安全机制分析的基础上,设计了802.16d标准安全系统的软件架构,并在Linux平台下以可动态加载的内核模块形式实现了其安全子层协议栈。通过仿真MAC层及PHY层的功能,对安全子层软件实现进行了性能验证及兼容性测试。结果表明,该系统完全实现了IEEE 802.16d标准的设计目标。

The security mechanism of IEEE 802.16 standard is analyzed,its security weakness and the improvements in the latest standard are also pointed out.Based on the analysis of the security mechanism,software architecture of 802.16d standard security system is proposed and its security protocol stack is implemented in the form of loadable kernel module of Linux.Performance and compatibility test of the software implementation are performed by simulating MAC and PHY layer,and the results indicate that the system can fully satisfy the design objectives of IEEE 802.16d standard.
