MIT researchers have devised a protocol to prevent man-in-the-middle attacks on wireless networks. The technique, Tamper-evident pairing, lets wireless radios automatically pair without the use of passwords. The researchers suggest that TEP could have detected the reported but still unconfirmed cellular attack that unfolded at Defcon conference earlier this month in Las Vegas. TEP can be used to protect communications between devices or between devices and base stations or access points, for any type of wireless connection.”]
