关键词： Side channel attack  

摘要： Existing ECC-based RFID authentication protocols exhibit vulnerabilities to various attacks. A new ECC-based authentication protocol is proposed to address these issues, ensuring mutual authentication, confidentiality, and resistance to SCA. The proposed protocol minimizes computational time and enhances privacy features without additional calculations. Security and privacy comparisons with existing schemes show the improved protocol's effectiveness in mitigating threats. The study emphasizes practical implementation and detailed security analysis, highlighting the protocol's efficiency and security enhancements. Further, it discusses emerging security solutions, including encryption algorithms, secure key exchange protocols, and anomaly detection techniques, to mitigate potential risks and enhance the overall security posture of IoT and RFID systems. By understanding and addressing these security concerns, organizations and individuals can fully leverage the transformative power of IoT and RFID technologies while safeguarding sensitive data and ensuring the integrity and reliability of interconnected systems. © 2025 Informa UK Limited, trading as Taylor & Francis Group.

摘要： At present, the performance of the traditional centralized coil antenna used for radio frequency identification(RFID) detection and localization of underground cables is insufficient, which seriously restricts the improvement of its detection and localization distance. A new type of high field strength distributed RFID coil antenna structure was proposed. Based on the derivation of antenna related electrical parameters, the magnetic field strength of the coil antenna was taken as the objective function, and its quality factor was fixed as the constraint condition. Particle swarm optimization algorithm was employed to optimize the number of turns of the coil antenna and the turn spacing between adjacent two turns. Finally, an experimental test platform was built. The test results show that compared with the traditional centralized RFID coil antenna, the distributed RFID coil antenna increases the reading distance by 33. 3%, significantly enhances the received signal strength indicator (RSSI) at the same distance, and helps to improve the accuracy of the underground RFID localization method based on RSSI, which provides an important reference for the application of RFID detection and localization of underground cables. © 2025 Beijing Kexue Jishu yu Gongcheng Zazhishe.

摘要： This work presents the design, analysis and experimental validation of a novel chip-based Ultra High Frequency Radio Frequency Identification (UHF RFID) sensing system designed for soil moisture measurement. The presented sensing resonator is integrated with Alien Higgs-3 IC having an impedance of 27.40-j200.9Y and operates at 915 MHz. The resonator is superimposed with a Kapton Polyimide sheet that acts as the smart sensing material for moisture detection. The proposed design is fabricated and tested in sandy soil with varying moisture levels. Variation of moisture content leads to changes in dielectric properties of the soil which is indicated by a consistent reduction in Received Signal Strength Indicator (RSSI) values. The change in RSSI further correlates to a consistent change in the impedance value of the sensor. Calibration curves establishing a relationship between RSSI levels and impedance are plotted against the known volumetric soil moisture content. This curve will be utilized to determine unknown soil moisture content in practical scenarios. © 2017 IEEE.

摘要： Metal cabinet environments, characterized by densely packed enclosures and strong multipath scattering, degrade read reliability for single-band UHF RFID systems. This paper introduces a miniature dual-band RFID tag antenna that incorporates anti-metal features through a stacked configuration. A folded dipole formed on lower layers serves the UHF band, and a dual-patch array on an upper layer covers the microwave band, both excited by a single inductively-coupled feed. This design reduces the antenna footprint from 170.0 × 140.0 mm2 to 76.0 × 33.5 mm2 (about an 89.3% decrease), meets chip impedances of 20 − j179 Ω at 915 MHz and 36 − j24 Ω at 2.45 GHz. Realized gains reach 1.2 dBi and 5.8 dBi on metal, with read ranges of 2.7 m (free space) and 7.8 m (on a 200 mm × 200 mm plate). Reliability tests in a server cabinet show that, under low power and high speed, 915 MHz drops to 48%, 2.45 GHz reaches 90%, and the dual-band setup sustains 100%, confirming the proposed design's robustness in confined metal-rich scenarios. © 2002-2011 IEEE.

摘要： In this paper, we demonstrate how the power-on-tag-forward (POTF) and reverse (POTR) resonance frequencies can be estimated simply by measuring changes in the autotune (AT) code of RAIN RFID chips capable of making capacitance adjustments for enhanced antenna impedance matching. We show how this approach allows us to reliably estimate these characteristic frequencies - and, by extension, the dielectric and magnetic properties - of objects using a simple reading of the AT state values in the chip memory. Therefore, we eliminate the need for full POTF and/or POTR curve measurement and the need for read distance estimation and environmental calibration. The proposed method shows repeatability using 6 diverse RAIN RFID tags with T-matched antenna designs and self-tuning ICs, deployed on 7 dielectrics and 1 magnetic material. Current limitations and future research directions are also discussed.

摘要： This paper presents a chipless radio frequency identification (RFID) tag with increased coding capability by using dual mode loop resonator (DMLR) (closed- and open-loop resonator) and dual band-notch ultra-wideband (UWB) antennas. 3N codes can be obtained by coupling N resonators of this kind with the microstrip. Through introducing the two band-notches on the UWB antenna, two more code bits can be performed without increasing the size of tag. Band notches on the antennas are designed in the lower frequency for high space efficiency. For verification, tag prototypes are fabricated and measured. The measured results show that 6 bits can be achieved within the band range of 4.0-5.9 GHz. © 2017 IEEE.
