Abstract

The invention discloses a wireless node blocking system which comprises a wireless node data package gathering module used for gathering a transmitted wireless node data package in wireless network, a wireless node analysis module used for analyzing wireless node information in the gathered wireless node data package and building a wireless network topological structure, a blacklist and whitelist judging module used for judging whether the wireless node needs to be blocked through a comparison between the wireless network topological structure and the blacklist or the whitelist, and a wireless node blocking module used for creating authentication data package for blocking a wireless access point. Through a comparison and a judgment of the blacklist and whitelist judging module, the wireless node analysis module can automatically analyze the wireless node which needs to be blocked, and only block the wireless node which needs to be blocked. Therefore, normal communications of other legal wireless nodes in the internet are guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a wireless node blocking system. Background technique [0002] Wi-Fi is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to each other. Wireless Internet access can avoid the trouble of wiring, and wireless Wi-Fi technology is relatively mature, more and more enterprises and individuals use wireless Wi-Fi to access the Internet. While wireless Internet access brings convenience, it is also accompanied by potential safety hazards. Once some illegal wireless nodes (that is, wireless nodes that are not allowed to access the wireless network) access the wireless network, they may occupy the Internet bandwidth of legitimate communication devices in the network, and steal data from other devices that access the Internet through the same wireless access point. Sensitive information, or the tra...
