摘要

Under the business environment, the ownership of an (Radio Frequency Identification, RFID) RFID tag embedded item often shifts, and the ownership of the corresponding item must also be transferred, so the privacy of the original owner and the new owner needs to be protected during the transfer of ownership. In order to protect the privacy of tag's ownership during the transfer process, an RFID tag's ownership transfer protocol base on bitwise operation (PSU-TOTP) is proposed. The proposed protocol uses bitwise cross-synthesis and cross-connect operations to encrypt the transmitted information and reduce the amount of computation at the tag. The flag FLAG is introduced to record the ownership of the current owner. The abstract description of the security model and protocol is given, and the proposed protocol is comprehensively analyzed to meet the corresponding security requirements under the security model. Security analysis shows that the proposed protocol meets the security requirements for the tag ownership transfer. The formalization of GNY logic proves the correctness of the proposed protocol. Performance analysis shows that the proposed protocol can effectively reduce the computational load on the tag side and achieve the goal of reducing the tag's cost. PSU-TOTP is suitable for low-cost RFID systems.
