Abstract
Unique temporary MAC addresses are calculated by mobile devices connected to wireless networks, using access point advertising information in combination with the permanent MAC address of the mobile device. The mobile devices use a hash function to construct a bit sequence from which a temporary MAC address can be extracted. The MAC address is unique over the entire region in which the mobile device can operate, without necessity of any coordination or negotiation between various access points of the region.
