随着科技的发展,无线局域网技术作为一种网络接入手段,迅速应用于需要在移动中联网和在网间漫游的场合,并为不易架设有线的地方和远距离的数据处理节点提供强大的网络支持。但是,无线局域网使用的传输媒介主要是电磁波,在一定的范围内可被任何人所接收,其安全性成为人们使用无线局域网最担心的问题。如何保证无线局域网的安全,已成为人们研究的重点。论文讨论了无线局域网的通信安全问题和一些有效的解决方案。 With the development of science and technology, wireless LAN technology, as a kind of network access method, is rapidly applied to the occasions that need to be roamed and roaming in the network and provide powerful data processing nodes that are difficult to set up a wired place and long distance Network support. However, the transmission medium used by wireless LANs is mainly electromagnetic waves and can be received by anyone within a certain range, and its security has become the most worrisome issue for people using wireless local area networks. How to ensure the safety of wireless LAN has become the focus of research. The paper discusses the wireless LAN security issues and some effective solutions.
