因特网与无线通信网的融合,正推动着全球无线互联网及其应用的高速发展,但如何保证网络的安全性是应首先考虑的关键问题。宽带无线接入网是无线互联网的一个重要组成部分,由于无线传输的特点,信息容易受到攻击和窃听,因此,无线宽带接入网的安全问题是整个无线互联网安全体系的重要组成部分,具有很重要的研究意义,必须在构筑无线宽带接入网基础结构体系时就对安全问题给予高度的重视。 本地多点分配系统(LMDS)作为一种固定无线宽带接入技术,已经成为国内外通信界的关注焦点之一,其安全问题也是其建设过程中应考虑的一个重要问题。然而,现有的LMDS系统几乎都没有考虑安全问题。作为指导新一代LMDS系统研制的IEEE 802.16标
The integration of the Internet and wireless communication networks is driving the rapid development of wireless Internet and its applications around the world. However, how to ensure network security is the key issue to be considered first. Broadband wireless access network is an important part of wireless Internet. Due to the characteristics of wireless transmission, information is easily attacked and eavesdropped. Therefore, the security of wireless broadband access network is an important part of the entire wireless Internet security system. Important research significance, we must pay attention to security issues in the construction of wireless broadband access network infrastructure system. As a fixed wireless broadband access technology, local multi-point distribution system (LMDS) has become one of the focuses of communication industry both at home and abroad. Its security problem is also an important issue that should be considered in its construction. However, almost all existing LMDS systems do not consider security issues. As a guide to the development of a new generation of LMDS system IEEE 802.16 standard
