摘要
IEEE 802.16是一种具有发展前景的宽带无线接入系统空中接口标准,但其安全机制仍存在不少问题,从而限制了其进一步发展。文中讨论了IEEE 802.16 Mesh模式中节点间的信任模型及建立连接的过程,并指出其中存在的安全漏洞。在此基础上,借鉴PGP中的自然人类社会的信任机制,改进了Mesh模式中节点间的信任模型,并提出了新的连接建立方式。分析表明新方式的安全性能要优于原方式。
The IEEE 802.16 air interface standard has the potential to achieve great market success, but its security issues restrict its further progress. So describes the trust model of the Mesh mode in the IEEE 802.16 networks and the process of establishing links among the nodes in the Mesh mode. Then presents potential threats in this process. Furthermore, by using the trust model of PGP, modifies the trust model of the Mesh mode in the IEEE. 802.16 networks, and also presents a new way to establish links among the nodes. Analysis shows that the new way is more secure than the original one.
