An Improved Secure RFID Authentication Protocol Using Elliptic Curve Cryptography

Radio-frequency identification technology is one of the critical technologies of the Internet of Things. It is a non-contact automatic identification technology. People tend only to pay attention to the accelerated development of its technology and ignore the security problems of the technology; radio-frequency identification technology development is no exception. Its security problems are becoming increasingly prominent. Because the radiofrequency identification system in the Internet of Things carries a large amount of user privacy information, its security problem will directly restrict the promotion and application of the Internet of Things. Therefore, the research of radio-frequency identification security authentication technology is significant to the healthy development of the Internet of Things. We propose an improved secure RFID authentication protocol using elliptic curve cryptography based on Izza et al.’s protocol. BAN logic is used to prove the improved protocol. Meanwhile, we carry out a comparative analysis of performance and efficiency. The results show that the improved protocol has higher security and lower calculation costs. © (2024) All Rights Reserved.
