Embodiment Construction

[0019] see figure 1 , two kinds of wireless access points (APs) are included in the wireless local area network of the present invention, namely the police AP1 and some access AP2s within the coverage of the police AP1, the access AP2 can issue its own identity information as required, and the police AP1 collects these information And make a judgment to confirm the legitimacy of the identity of each access AP2 in the local area network. The police AP1 will periodically scan its coverage area and perform a protocol interaction with the scanned access AP2. If the interaction is successful, it is a legal access AP. He will record the data as a backup. If the interaction is unsuccessful, it will judge It may be an illegal AP, and an alarm will be sent to the network management. In this way, in a local area network, if the access AP2 supports identity reporting, and several police AP1s with the ability to collect and report information are properly placed, when an illegal AP acces...

Abstract

This invention relates to a method for detecting illegal wireless AP in wireless LAN designing multiple police AP and multiple acc AP, the said police AP detects the acc AP in its covery field and asks the acc AP to answer the detection request and judges the legal identity of the acc AP accordingly, the illegal acc AP can't answer the identity certification information, the police AP informs the network manager to dismantle it so as to guarantee safety of the wireless LAN.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for detecting and discovering an illegally accessed wireless access point (Wireless Access Point) in a wireless local area network. Background technique [0002] With the vigorous development of computer technology and network technology, the application of network in all walks of life is more and more extensive. Wired network has a high reputation and market share in the market due to its high transmission speed, numerous product brands and quantities, and rapid technological development. However, with the maturity of wireless network technology, the continuous increase of product categories and the decline of product costs, in the next few years, wireless networks will have a greater development in the world. There are more and more applications of wireless LAN, which will extend wired LAN or replace it in some cases. It can be expected that in the future era of ubiquitous ...
