“…As low-cost tags do not possess an on-chip clock, a capacitor's discharge time [77] can be enough for a rough estimate of the round trip time (distance). Alternatively, a clock recovery circuit based on a phase-locked loop can be used, as shown in the prototype designed by Bo et al [7]. Independently of the approach followed, in our proposal a certain degree of inaccuracy (e i ) regarding distance (d i ) does not represent a major security risk.…”

The design of a secure RFID identification scheme is a thought-provoking challenge, and this paper deals with this problem adopting a groundbreaking approach. The proposed protocol, called Noent, is based on cryptographic puzzles to avoid the indiscriminate disclose of the confidential information stored on tags and on an innovative role reversal distance-bounding protocol to distinguish between honest and rogue readers. The protocol provides moderate privacy protection (data and location) to single tags but its effectiveness increases hugely when it is used to protect a large population of tags (e.g., protection against inventory disclosure). Moreover, in comparison with classical approaches, Noent does not require an online database, which facilitates key updating and mitigates desynchronization attacks.

“…The difference between two clocks at any point in time is called clock skew and is due to both clock drift and the possibility that the clocks may have been set differently on different machines. It has been studied in [21,22,23] that the frequency deviation for NFC and RFID working at 13.56MHz is about 1% . This frequency deviation is inevitable and may also change in different devices, and be affected by environmental factors such as temperature and circuit ageing.…”

Near Field Communication (NFC) is a promising short distance radio communication technology for many useful applications. Although its communication range is short, NFC alone does not guarantee secure communication and is subject to security attacks, such as eavesdropping attack. Generating a shared key and using symmetric key cryptography to secure the communication between NFC devices is a feasible solution to prevent various attacks. However, conventional Diffie-Hellman key agreement protocol is not preferable for resource constrained NFC devices due to its extensive computational overhead and energy consumption. In this paper, we propose a practical, fast and energy-efficient key agreement scheme, which uses random bits transmission with waveform shaking, for NFC devices by exploiting its off-the-shelf full-duplex capability. In the proposed method, two devices send random bits to each other simultaneously without strict synchronization or perfect match of amplitude and phase. On the contrary, the method randomly introduces synchronization offset and mismatch of amplitude and phase for each bit transmission in order to prevent a passive attacker from determining the generated key. A shared bit can be established when two devices send different bits. We conduct theoretical analysis on the correctness and security strength of the method, and extensive simulations to evaluate its effectiveness. We build a testbed based on USRP software defined radio and conduct proof-of-concept experiments to evaluate the method in a real-world environment. It shows that the proposed method achieves a high key generation rate of about 26kbps and is immune to eavesdropping attack even when the attacker is within several centimeters from the legitimate devices. The proposed method is a practical, fast, energy-efficient, and secure key agreement scheme for resource-constrained NFC devices.

“…However, the solutions OE2 4 only provide a discontinuous clock because of the "pause" generated by OOK modulation in the carrier. Although Reference [5] can provide the consecutive clock, low sensitivity to OOK signal leads to high frequency deviation, which increases the probability of error demodulation. In particular, under the mobile payment application, it tends to fail due to the weak OOK signal.…”

This paper presents a fully integrated carrier clock recovery circuit for a mobile payment application. The architecture is based on a sampling-detection module and a charge pump phase locked loop. Compared with clock recovery in conventional 13.56 MHz transponders, this circuit can recover a high-precision consecutive carrier clock from the on/off keying (OOK) signal sent by interrogators. Fabricated by a SMIC 0.18-m EEPROM CMOS process, this chip works from a single power supply as low as 1.5 V. Measurement results show that this circuit provides 0.34% frequency deviation and 8 mV sensitivity.
