Abstract— RFID tags will exist pervasively in our daily lifein a near future. In RFID systems, privacy and security areof critical importance to avoid potential tracking abuse andprivacy violations. Many protocols have been proposed toaddress privacy and security issues in RFID systems.Physical attacks receive few considerations from the currentresearch. Through physically attacks, attackers can get thesecret identification-related information stored on RFIDtags, and can later use the obtained information toimpersonate legitimate readers for illegal tracking. In thispaper we describe a threat model of RFID systems andpresent a detailed analysis of physical attacks on RFID tagsand other security threats. We propose a secure identityreporting protocol to address these threats. Our securityand performance analysis show that the proposed protocolcan defeat physical attacks, in addition to other securitythreats, and scale well to large RFID systems.
