Abstract
A method for detecting address rotation by a device in a communication network includes receiving, at a first time, a first message transmitted by the device, receiving, at a second time, a second message transmitted by the device, and processing the first message to determine a first sequence number and a first transmitter address. The method also includes processing the second message to determine a second sequence number and a second transmitter address, determining that the second transmitter address is different from the first transmitter address, determining a time gap between the first time and the second time, and determining, based, in part, on the time gap, a sequence threshold value. The method further includes determining a sequence difference between the first sequence number and the second sequence number, determining that the sequence difference is less than the sequence threshold value, and providing an indication of address rotation by the device.
