Tracking Loop Distortion of BDS‐3 B1C Signal in Spoofing Scenarios: An Experimental Analysis

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study established a feeder‐based BDS spoofing experimental platform and uses multi‐correlator tracking to systematically analyse the tracking loop distortion characteristics of BDS‐3 B1C signals under position and time spoofing, comparing differences between narrowband (NB) and wideband (WB) tracking modes.

Calculation of the lower limit of the spoofing-signal ratio for a GNSS receiver-spoofer

EURASIP Journal on Wireless Communications and Networking, 2018
A receiver-spoofer is one of the most covert global navigation satellite system (GNSS) spoofing attacks and can only be effectively detected by the combination of multiple anti-spoofing technologies.

Towards a Secure Central Bank Digital Currency System: A Case Study of Tanzania

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study proposes a secure, context‐specific design for a Central Bank Digital Currency (CBDC) system for Tanzania, grounded in stakeholder input and empirical data. It identifies key adoption barriers in digital financial services, namely, security and privacy concerns and high transaction fees, and suggests how a well‐designed CBDC might address ...

Generative Domain Adaptation for Face Anti-Spoofing

, 2022
Face anti-spoofing (FAS) approaches based on unsupervised domain adaption (UDA) have drawn growing attention due to promising performances for target scenarios. Most existing UDA FAS methods typically fit the trained models to the target domain via aligning the distribution of semantic high-level features. However, insufficient supervision of unlabeled
