With the decreasing price of wireless products and the rising number of users, for example, in the airport, cafeteria and other public area, have already set wireless AP(input point), and for the new laptops, such as Centrino laptop, with builtin wireless work card, people can access Inter wherever and whenever they , wireless work brings us hidden trouble as well as the convenience and fortableness ,Imagine this: if an enterprise work has a perfect protection system, which is consisted with firewall, IPS,VPN, DMZ, it approaches to impossibility to destroy it from outer side。 however, if someone who is working in the pany take his own AP to the pany, connect it into Inter and use it, just for convenience or for fun, with the help directional antenna, the intruders can skirt around levels of protection of the wire work one hundred or several hundred meters away, join in internal works of this pany, therefore,the tremendous costs on the enterprise work will be valueless. In the early stage of development, the filter of physical address (MAC) and matching of service area identifier (SSID) matching are two key techniques of security. Physical address filtering technology can realize filtering of physical address by protecting a list of accessible MAC address in the wireless access point AP. The matching of identifier in the service area requires wireless stations show correct SSID, only in this way can it access to AP. Through the password authentication, to achieve a certain levels of wireless safey. KEY WORDS: wireless work setting, service area identifier (SSID), WEP security, wireless routing III 目 錄 第一章 緒論 .................................................................................................................................... 1 課題的來源及意義 ............................................................................................................... 1 課題主要研究的問題 ............................................................................................................ 1 ......................................................................................................... 1 目標(biāo) .......................................................................................................................... 1 基本思路 ................................................................................................................... 2 第二章 無(wú)線局域網(wǎng)技術(shù) ................................................................................................................... 3 ............................................................................................................ 3 傳輸方式 ................................................................................................................... 3 網(wǎng)絡(luò)拓?fù)?................................................................................................................... 4 網(wǎng)絡(luò)接口 ................................................................................................................... 5 無(wú)
