Privacy-Aware Multi-Context RFID Infrastructure Using Public Key Cryptography
We propose a novel approach in designing an RFID infrastructure which foresees the usage of a single RFID tag within different contexts and for multiple purposes. We regard privacy as one of the most important design issues and show that an infrastructure for multi-purpose RFID tags to be used in different contexts can be implemented in a privacy preserving manner. We address security attacks such as cryptanalytic, impersonation, tracking, replay, and relay and show that the protocols used in the proposed infrastructure are secure against them. We also introduce a new angle to privacy in RFID systems by presenting spatio-temporal attacks as an important threat against privacy. We propose a methodology to thwart or alleviate these kinds of attacks. We develop our multi-context RFID infrastructure relying on usage of public key cryptography (PKC), which presents more scalable solutions in the sense that the backend servers can identify the tags 75 times faster than best symmetric cipher ...
