“…When two tags are placed in close proximity, both radiative and inductive coupling are present. RF-Mehndi [21] and Hu-Fu [22] are designed both based on the inductive coupling between tags. To verify the inductive coupling, we do some experiments between two tags and the experimental results are shown in Figure 5.…”

“…Resisting replay attack, Hu-Fu [22] adds a random signal during the communication between the reader and tags and extracts the power spectral density (PSD) and energy spectrum of two tag signals as features of authentication. RF-Mehndi [21] introduces human biological features, authenticating both the tag and the tag holder. All the above methods have a common flaw that the system cannot resist replay attack and impersonation attack simultaneously.…”

Currently, Radio Frequency Identification (RFID) is one of the key technologies to realize the Internet of Things (IoT), which is widely used in our daily life. However, there are some security threats such as impersonation attack, replay attack in existed RFID systems. In addition, most physical-layer authentication methods for RFID systems are mainly to authenticate tags without authenticating the user. In this paper, we present the design and implementation of Au-Hota, a system that can authenticate the tag and the user simultaneously, and can resist replaying attack and impersonation attack that cannot be solved by most physical-layer methods. Our idea is to assign a unique identifier to the user based on the inductive coupling between two adjacent tags. When the user draws the identity identifier on the tag, different identity identifiers correspond to unique phase features so that simultaneous authentication of the tag and the user can be achieved under the premise of ensuring security. The system is fully compatible with Ultra High Frequency (UHF) RFID systems without any modification. We implement a prototype of the system and conduct extensive experiments to evaluate performance. Our results demonstrate that the system has good authentication performance.

“…Hu-Fu [19] uses the inductive coupling of two tags to fingerprint them. RF-Mehndi [20] identifies an RFID card and its user simultaneously by exploring the backscattered signal changes induced by the user's fingertip on a specially build passive tag array. RF-Rhythm explores COTS RFID tags and is complimentary to the above work.…”

RF-Rhythm: Secure and Usable Two-Factor RFID Authentication

Passive RFID technology is widely used in user authentication and access control. We propose RF-Rhythm, a secure and usable two-factor RFID authentication system with strong resilience to lost/stolen/cloned RFID cards. In RF-Rhythm, each legitimate user performs a sequence of taps on his/her RFID card according to a self-chosen secret melody. Such rhythmic taps can induce phase changes in the backscattered signals, which the RFID reader can detect to recover the user's tapping rhythm. In addition to verifying the RFID card's identification information as usual, the backend server compares the extracted tapping rhythm with what it acquires in the user enrollment phase. The user passes authentication checks if and only if both verifications succeed. We also propose a novel phase-hopping protocol in which the RFID reader emits Continuous Wave (CW) with random phases for extracting the user's secret tapping rhythm. Our protocol can prevent a capable adversary from extracting and then replaying a legitimate tapping rhythm from sniffed RFID signals. Comprehensive user experiments confirm the high security and usability of RF-Rhythm with false-positive and false-negative rates close to zero.
