Eavesdropping Against Bidirectional Physical Layer Secret Key Generation in Fiber Communications (2022)
Presentation / Conference Contribution
Hu, W., Wei, Z., Leeson, M., & Xu, T. (2022, November). Eavesdropping Against Bidirectional Physical Layer Secret Key Generation in Fiber Communications. Presented at 2022 IEEE Photonics Conference (IPC), Vancouver, BC, Canada

Physical layer secret key exploits the random but reciprocal channel features between legitimate users to encrypt their data against fiber-tapping. We propose a novel tapping-based eavesdropper scheme, leveraging its tapped signals from legitimate us...

Secret Key Rate Upper-bound for Reconfigurable Intelligent Surface-combined System under Spoofing (2022)
Presentation / Conference Contribution
Wei, Z., Wang, L., & Guo, W. (2022, September). Secret Key Rate Upper-bound for Reconfigurable Intelligent Surface-combined System under Spoofing. Presented at 2022 IEEE 96th Vehicular Technology Conference (VTC2022-Fall), London, United Kingdom

Reconfigurable intelligent surfaces (RIS) have been shown to improve the secret key rate (SKR) for physical layer secret key generation (PL-SKG), by using the programmable phase shifts to increase reciprocal channel entropy. Most current studies cons... Read More about Secret Key Rate Upper-bound for Reconfigurable Intelligent Surface-combined System under Spoofing.

Revealing the Excitation Causality between Climate and Political Violence via a Neural Forward-Intensity Poisson Process (2022)
Presentation / Conference Contribution
Sun, S. C., Jin, B., Wei, Z., & Guo, W. (2022, July). Revealing the Excitation Causality between Climate and Political Violence via a Neural Forward-Intensity Poisson Process. Presented at Thirty-First International Joint Conference on Artificial Intelligence {IJCAI-22}, Vienna, Austria

The causal mechanism between climate and political violence is fraught with complex mechanisms. Current quantitative causal models rely on one or more assumptions: (1) the climate drivers persistently generate conflict, (2) the causal mechanisms have...

Graph Layer Security: Encrypting Information via Common Networked Physics (2022)
Journal Article
Wei, Z., Wang, L., Sun, S. C., Li, B., & Guo, W. (in press). Graph Layer Security: Encrypting Information via Common Networked Physics. Sensors, 22(10), Article 3951. https://doi.org/10.3390/s22103951

The proliferation of low-cost Internet of Things (IoT) devices has led to a race between wireless security and channel attacks. Traditional cryptography requires high computational power and is not suitable for low-power IoT scenarios. Whilst recentl...

A Multi-Eavesdropper Scheme Against RIS Secured LoS-Dominated Channel (2022)
Journal Article
Wei, Z., Guo, W., & Li, B. (2022). A Multi-Eavesdropper Scheme Against RIS Secured LoS-Dominated Channel. IEEE Communications Letters, 26(6), 1221-1225. https://doi.org/10.1109/lcomm.2022.3166239

Reconfigurable intelligent surface (RIS) has been shown as a promising technique to increase the channel randomness for secret key generation (SKG) in low-entropy channels (e.g., static or line-of-sight (LoS)), without small-scale fading. In this let... Read More about A Multi-Eavesdropper Scheme Against RIS Secured LoS-Dominated Channel.

Robust Time Synchronization for Industrial Internet of Things by H ∞ Output Feedback Control (2022)
Journal Article
Zong, Y., Dai, X., Wei, Z., Zou, M., Guo, W., & Gao, Z. (2023). Robust Time Synchronization for Industrial Internet of Things by H ∞ Output Feedback Control. IEEE Internet of Things Journal, 10(3), 2021-2030. https://doi.org/10.1109/jiot.2022.3144199

Precise timing over timestamped packet-exchange communication is an enabling technology in the mission-critical industrial Internet of Things (IIoT), particularly when satellite-based timing is unavailable. The main challenge is to ensure timing accu... Read More about Robust Time Synchronization for Industrial Internet of Things by H ∞ Output Feedback Control.
