RFID Tag Ownership Transfer Protocol using Blockchain

摘要

Aiming at the security issues of radio frequency identification (RFID) tags during its life cycle, we propose a new RFID tag ownership transfer protocol based on blockchain in this paper. In order to guarantee the safety of session messages, the protocol uses a hash function and blockchain technology to protect information. During the authentication process, a Merkle hash tree can quickly verify the data of blockchain. Due to decentralization of blockchain, the protocol guarantees the security of RFID systems without the participation of a trusted third party (TTP). The identity of tags is confirmed by a pseudonym, and its real identity is not disclosed to an untrusted entity such as the reader. Finally, the formalization analysis based on GNY logic is given. Detailed security analysis has been performed to prove that the proposed protocol can resist impersonation, replay, tracking, and de-synchronization attacks.
