PIANO: Proximity-based User Authentication on Voice-Powered Internet-of-Things Devices

, 2017
Voice is envisioned to be a popular way for humans to interact with Internet-of-Things (IoT) devices. We propose a proximity-based user authentication method (called PIANO) for access control on such voice-powered IoT devices.

Spoofing Attack Results Determination in Code Domain Using a Spoofing Process Equation

Sensors, 2019
When a user receiver is tracking an authentic signal, a spoofing signal can be transmitted to the user antenna. The question is under what conditions does the tracking point of the receiver move from the authentic signal to the spoofing signal?

Ultrathin Broadband Terahertz Metamaterial Absorber Based on Multimode Spoof Localized Surface Plasmon Resonators

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
This work presents an ultrathin terahertz metamaterial absorber that achieves broadband and polarization‐insensitive performance through multimode spoof‐plasmon resonances and tunable indium tin oxide loss engineering. The absorber offers near‐Rozanov‐limit thickness and optical transparency, enabling integration into compact and multifunctional THz ...

Time‐Domain Near‐Field Scanning Microscopy of Terahertz Metasurfaces

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Time‐domain near‐field scanning terahertz microscopy provides direct access to subwavelength electromagnetic fields on metasurfaces. By combining controlled polarization excitation with nanoscale probing, this technique enables quantitative visualization of localized hotspots, surface‐wave propagation, and wavefront manipulation, offering a powerful ...

Detection of Induced GNSS Spoofing Using S-Curve-Bias

Sensors, 2019
In Global Navigation Satellite System (GNSS), a spoofing attack consists of forged signals which possibly cause the attacked receivers to deduce a false position, a false clock, or both.
