At present, with the increasingly growing application of Internet of Things, virtualization and intelligent technologies, and the maturity of smart campus systems, campus card technology based on radio frequency identification (RFID) has developed rapidly. Due to the convenience of use, it is widely used in dormitory access control system, book borrowing system, attendance system, and payment system. Because the data carried by the RFID card is more and more complex, the requirements for its security are getting higher and higher. In order to solve the problem of identity authentication and privacy protection of the RFID application existed in the digital campus in recent years, an improved mutual authentication protocol in mobile RFID for smart campus is put forward by analyzing and studying existing smart campus authentication protocols based on hash algorithm, which uses the technology of random number S and time stamp T. This protocol implements mutual authentication among the tag, reader, and backend database without the premise that the signal path between the database and reader communication is a safe signal path and can effectively resist counterfeit attack, replay attack, position tracking attack, de-synchronization attack, eavesdropping attack, denial of service attack, and man-in-the-middle attack, and it can also guarantee forward security. Due to the large data operations and storage have been transferred to readers and backend data, the protocol is formally proved to have a strong reliability and a good security. In addition, through the comparison with other existing authentication protocols on the resident variable storage overhead, the cost of computing complexity and the security performance, the authentication protocol proposed in this paper has a better storage and calculation performance, and it can better satisfy the security requirements in mobile RFID applications for smart campus in the future and has a good application prospect.

A New Mutual Authentication Protocol in Mobile RFID for Smart Campus

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.
