1. A method of detecting address spoofing in a wireless network, comprising the following steps:
- capturing frames transmitted over the wireless network, having an address field that comprises an address of a network access point;
analyzing the captured frames to establish a first list of stations associated with said access point;
obtaining from said access point a second list of stations that are associated with it; and
comparing the first and second lists of stations.

Abstract
The invention relates to a method, device and program for detection of address spoofing in a wireless network. According to the invention, a sensor is installed in order to capture frames transmitted over the wireless network which have an address field comprising an address of a network access point. The captured frames are analyzed in order to establish a list of stations that are associated with the access point. Another list of stations associated with the access point is obtained from the latter. The two station lists are compared in order to detect possible access point address spoofing.

14. A computer program to be installed in a device interfaced with at least one access point of a wireless network and with a sensor to help in detecting address spoofing in the wireless network, to be run by a processing unit of said device, the program comprising instructions for executing the following steps when the program is run by said processing unit:
-
receiving from the sensor identification information originating from the frames captured by the sensor on the wireless network, the captured frames having an address field that comprises an address of the access point, said received identification information corresponding to a first list of stations associated with said access point; obtaining from said access point a second list of stations that are associated with it; and comparing the first and second lists of stations.
