IEEE802.16标准安全机制研究

Security Mechanism of IEEE 802.16

作为无线城域网的标准,IEEE802.16已经取得了巨大进展,但是无线信道自身的弱点使得802.16的安全问题依然受到关注。本文在对802.16标准安全机制进行分析的基础上,指出了803.16d存在的安全问题以及802.16e所作的改进,并对未来要解决的问题提出建设性的意见。

Although IEEE 802.16, a protocol for wireless metropolitan area network（WMAN）, has achieved a lot, it is still paid much attention because of open features of wireless channel. After analyzing security mechanism of 802.16, this article points out the problems of 802.16d and improvement of 802.16e, and gives some good advice for the unsolved problems.
