  • Method and system for detecting masquerading wireless devices in local area computer networks
    Patent number: 7856656
    Abstract: Methods and systems for detecting a masquerading wireless device in a local area network are provided. The method includes receiving a first packet and a second packet. Preferably, the first packet includes a first identity information and a first time information, and the second packet includes a second identity information and a second time information. The method can compute, using the first time information, a first approximation to a starting time of a wireless device associated with the first identity information. The method can also compute, using the second time information, a second approximation to a starting time of a wireless device associated with the second identity information. The method further includes determining whether a masquerading wireless device is present in the local area network based on at least the first and second approximations.
