Abstract
Protocols for Radio Frequency Identification (RFID) tags take care to address privacy and security, particularly with regard to an outside adversary. RFID tagged items can change owners (for example, in a supply chain), introducing the new challenge of maintaining privacy of the old owner and the new owner from each other given that each has tag identifiers and secrets. We present the Responsive Tag Ownership Transfer Protocol (RT-OTP). Using an authentication secret established by the old owner and using a trusted third party that shares a secret with the tag, the protocol builds a new secret shared by new owner and tag without the old owner being able to obtain the secret and simultaneously preventing the new owner from discerning the secret formerly shared by the old owner and tag. We establish that RT-OTP resists attacks on privacy and security while keeping resources within the bounds for passive tags in the EPC C1G2 standard.
