Abstract

The embodiment of the invention discloses a method and device for detecting the karma attack, and relates to the technical field of wireless networks. The method and the device solve the problem that in the prior art, the karma attack on a user device may happen when the user device has access to the WIFI. The method for detecting the karma attack includes the steps of judging whether the user device has had access to the Wifi or not, detecting whether a karma attack device exists around the user device or not if the user device has not had access to the Wifi, and detecting whether the Wifi hotspot which the user device has access to is the karma attack device or not if the user device has had access to the Wifi. The method and the device are mainly used for detecting whether the karma attack happens to the user device when the user device has access to the Wifi.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method and device for detecting karma attacks. Background technique [0002] At present, when people use user equipment such as mobile terminals or PCs to access the Internet, they often use WIFI (WIreless-Fidelity, wireless fidelity) to connect to the network. Regardless of whether it is a mobile device or a PC, as long as it is a WIFI hotspot that has been connected, it will be automatically saved. The next time these hotspots appear in the same area, the user device will automatically connect again. [0003] In order to speed up the connection, the user equipment will broadcast the ESSID (Extended Service Set Identifier, Extended Service Set Identifier) ​​of all WIFI hotspots that it has ever connected to. For example, if the user equipment has been connected to WIFI hotspots such as CMCC and Airport Free, the user equipment will actively broadcast the connected W...
