ABSTRACT

Extremely limited in computational and energy capability, radio-frequency identification (RFID) tags, especially passive tags, can hardly authenticate the scanning readers. Thus, information leakage of RFID tags is one of the most challenging problems holding back users’ confidence in adopting RFID technologies. In this chapter, we propose Smart RFID Keeper (SRK)—an off-tag RFID data access control mechanism, which is installed in RFID-enabled environments to regulate RFID scanning. To solve the information leakage threat, SRK is designed to (1) authenticate the user, (2) detect and counter unauthorized accesses to RFID tags, and (3) enforce fine-grained access policy.
