无线城域网IEEE 802．16标准的安全性研究

RESEARCH ON THE SECURITY IN WMAN IEEE 802.16

IEEE于2004年通过了802.16d,以满足无线宽带接入市场的需要。为了进一步提高802.16d的安全性,首先分析了802.16d的协议栈结构及其各子层的作用,然后介绍了802.16d已有的安全机制,其中详细介绍了安全关联SA和PKM协议,最后分析了802.16d仍然存在的安全缺陷,并且提出了相应的改进措施。

IEEE proposed a new standard called 802.16d in 2004 to meet the requirement of Broadband Wireless Access. In order to enhance the security of 802.16d further,the structure of the protocol in 802.16d is analyzed. Then,the security mechanism implemented by 802. 16d is introduced,and the security association and the PKM protocol are introduced in detail. Finally, some still existed security deficiencies are revealed, and some corresponding improvements are proposed.
