Abstract
RFID technology is a pervasive technology because it is being used in many systems. RFID provides very good solution for non-business areas as well. However, its unprotected data in wireless communication channel and mobility of RFID tags opens up many possibilities of these tags being tracked by unauthorized reader which violates location privacy. It also gives opportunity for unauthorized user to access confidential data. Past works on RFID with privacy-preserving solution have dealt with lots of issues regarding system integrity and availability. In this paper we present A Unified Model for Security, Trust and Privacy (STP) of RFID System. Our proposed model use trusted computing principles and components to solve issues highlighted by previous works in RFID protocols. We combine the strengths of encryption, mutual attestation and privacy enhancement to form a unified model for RFID system.
