Mutual Attestation Using TPM for Trusted RFID Protocol

The massive deployment of RFID tag to various systems raises some issues regarding security and privacy. RFID system without trust enhancement poses security threat because secret data can be easily revealed to adversary system by due to unverified platform. Numerous works revealed that the unverified RFID platform can be compromised either by malicious codes or man in the middle attack. For such an open, unverified RFID platform, system integrity verification for RFID reader, back-end server and tag has to be implemented in order to enhance system trust. The proposed back-end server and RFID reader with the embedded trusted computing technology will enhance the system integrity measurements and verifications. In this paper we propose a mutual attestation for trusted RFID protocol by using trusted platform module (TPM) and AES encryption for encrypting data transfers within the trusted RFID system. We also highlight the importance of trusted computing technology towards solving the privacy and security issues.
