Executive Summary

Although RFID systems offer many noteworthy characteristics, security and privacy issues associated with them are not easy to address. In this paper, the authors investigate how to solve the eavesdrop-ping, modification and one particular type of relay attacks toward the tag-to-reader communication in passive RFID systems without requiring lightweight ciphers or secret credentials shared by legitimate parties using a physical layer approach. To this end, they propose a novel physical layer scheme, called Backscatter modulation- and Uncoordinated frequency hopping-assisted Physical Layer Enhancement (BUPLE).
