In this paper, the authors report on a new approach for enhancing security and privacy in certain RFID applications whereby location or location-related information (such as speed) can serve as a legitimate access context. Examples of these applications include access cards, toll cards, credit cards, and other payment tokens. They show that location awareness can be used by both tags and back-end servers for defending against unauthorized reading and relay attacks on RFID systems. On the tag side, they design a location-aware selective unlocking mechanism using which tags can selectively respond to reader interrogations rather than doing so promiscuously.
