Abstract: Aiming at security and privacy protection problems faced in the existing RFID authentication protocol, this paper proposes a efficient RFID security authentication protocol based on Hash which can resist the denial of service attack. Using the comparison and recognition of random number on the reader, the protocol can resist the denial of service attacks. And two states of label identifier are stored in the database, in order to realize the electronic tag and the backend database data synchronization. Meanwhile, this paper theoretically analyzes the performance and security of the protocol, and the security of the protocol is formally proved by BAN logic. The analysis shows that the protocol can achieve effective mutual authentication between reader and electronic tag, and it can effectively resist the denial of service attack, and compared with other protocols it reduces the amount of calculation of RFID system. It is suitable for large-scale RFID system using electronic tags.
