Adaptive RLWE-Based Lightweight Mutual Authentication Protocol for Medical RFID Systems

Dazhong Liu, Shanshan Tu, Kun Li +2 more

Radio Frequency Identification (RFID) is now widely used in medical Internet of Things (IoT) systems. As its use grows, protecting patient data has become a major concern. The rise of quantum computing makes this challenge even more serious. In this paper, we present an adaptive and lightweight mutual authentication protocol for medical RFID systems. The protocol is based on the Ring Learning With Errors (RLWE) problem, which provides strong post-quantum security. It introduces an adaptive mechanism that adjusts RLWE parameters for tags with different security needs. This design achieves a balance between protection and resource use. To improve robustness, the protocol also includes a pseudonym update process that prevents desynchronization. We analyze its security in detail. The analysis combines a formal proof in the Random Oracle model and symbolic verification with the Scyther tool. Results show that the protocol can resist replay, man-in-the-middle, and impersonation attacks. It also preserves tag anonymity and forward secrecy. Performance tests further confirm its efficiency. On the tag side, the average computation time is only 7.67931 ms. These results suggest that the protocol is well-suited for secure and efficient authentication in resource-limited medical RFID environments under post-quantum threats.

A safe radio frequency identification system (RFID) authentication protocol for Internet of Things

Zhiguo Du, Bin Wen, Zhihui Wu +2 more

Abstract Internet of Things (IoT) is the evolution of related technologies and applications such as Internet and mobile networks. Agriculture, as the source of food, is one of the key areas for the application of the IoT technology, and it is also the field with the most urgent, difficult and integrated characteristics of the IoT application. Future research into IoT will focus on generic technology, information security, and critical applications. Based on IoT, the existing Radio frequency identification system (RFID) security mechanisms are analyzed, with a focus on cryptographic protocols. Investigate the weaknesses or flaws in these protocols, and then a theoretical model and method to design and analyze RFID protocols within the provable security framework is discussed. A mutual authentication protocol of RFID system using synchronized secret information is put forward.
