随着人们对降低成本和获得移动性需求的日益增长,无线局域网的用户数量也正在迅速增加,无线局域网也早已成为人们日常生活不可分割的部分。无线局域网是无线技术与局域网技术相结合的产物。它为数据通信提供一种灵活的方式,但也正是其灵活性引发一些威胁用户隐私和安全的问题。在阐述无线局域网概况的基础上,总结无线局域网存在的三类安全威胁,并归纳现有的一些解决方法,最后就无线局域网的发展提出几点建议。
With the increasing demand for reducing costs and obtaining mobility, the number of wireless LAN users is also rapidly increasing, and wireless LANs have long been an integral part of people’s daily life. Wireless LAN is a combination of wireless technology and LAN technology. It provides a flexible way for data communications, but it is also its flexibility that raises issues that threaten the privacy and security of users. Based on the overview of wireless LAN, this paper summarizes the three kinds of security threats existing in wireless LAN, and summarizes some existing solutions. Finally, it puts forward some suggestions on the development of wireless LAN.
