Third Prize of the Best Student Presentation Award in International Conference on Optical and Photonic Engineering 2022

Our PhD student, Miss Zilan Pan, obtained the Third Prize of the Best Student Presentation Award in the International Conference on Optical and Photonic Engineering (icOpen) 2022 for the paper “Optical Transmission through Thick Biological Tissue using Optical Modulation”. Accurate data transmission is important in biological applications and biomedical devices. Realizing high-fidelity optical wireless transmission with a large penetration depth is desirable. Here, a sequence of amplitude-only patterns at the transmitter is considered as information carrier to encode the transmitted data. The total light intensity at the receiving end is collected and recorded by a bucket detector. Miss Pan’s research work verifies feasibility and effectiveness of the proposed approach with different thicknesses of a biological sample. The experimental results demonstrate the proposed method based on zero-frequency modulation using low light intensity.

EEE Scholars ranked among World’s Top 2% Most-cited Scientists

Congratulations to the following EEE scholars who have been ranked among the top 2% of the most-cited scientists in the world in their respective fields, as compiled by Stanford University. The “top 2%” achievement was based upon standardised field-citation metrics including the total number of citations, h-index factor, co-authorship-adjusted hm-index, and citations to papers in different authorship positions to arrive at an overall composite score. The Department is very proud to acknowledge them as world-leading scientists!

Best Paper Award in the 16th International Conference on Provable and Practical Security 2022

Dr Wenjuan Li and her research collaborators from the Technical University of Denmark won the Best Paper Award in the 16th International Conference on Provable and Practical Security (ProvSec) 2022 for their paper "FolketID: A Decentralized Blockchain-based NemID Alternative against DDoS Attacks". ProvSec is an international conference on provable security in cryptography and practical security for information systems. Electronic Identity (eID) is a solution toward solving the identity problem when deploying e-Government. Such solution should not only be secure, but also have to be robust enough under adversarial conditions. In practice, eID often suffers from some security threats such as Distributed Denial of Service (DDoS) attack. NemID is a digital eID used to log into public websites in Denmark. Dr Li's research team developed FolketID, a blockchain-based NemID alternative against DDoS attacks. The DDoS mitigation is achieved by not only utilizing its powerful data distribution ability, but also exploiting the economy system in blockchain. It particularly takes use of the transaction fees to effectively prevent DDoS attacks. The results demonstrate the viability and effectiveness of FolketID in defeating DDoS attacks.

Outstanding Student Award in the IEEE International Conference on Digital Twins and Parallel Intelligence (DTPI’2022)

Supervised by Dr Ivan Ho, our MSc in EIE programme graduate, Miss Tingting Fan, obtained the Outstanding Student Award in the IEEE International Conference on Digital Twins and Parallel Intelligence (DTPI) 2022 for her research work on "Digital Twin-Assisted Lane-changing and Variable Speed Limit Control for Weaving Segments". In this work, a joint traffic and network simulator is established to construct the digital twin system, and two traffic control strategies, namely the lane-changing (LC) distribution strategy and the variable speed limit (VSL) control strategy, are proposed and validated in a complex highway weaving segment environment. The results show that communication packet loss negatively affects the performance of V2X-assisted LC control, which is usually neglected in the field of transport studies. However, by integrating the LC control with the proposed reinforcement learning based VSL control, we can improve the overall average speed of vehicles on highway weaving segments by more than 40% compared with the LC control alone.

Champion of Hack The Boo CTF Competition

Hack The Boo CTF Competition is a 5-day Catch-the-flag event organized by Hack The Box, a renowned global cybersecurity training platform which allows individuals, companies, universities and all kinds of organizations around the world to level up their hacking skills. This year, they organized a Halloween-themed CTF in the Cybersecurity Awareness Month in October 2022, which challenged contestants for a variety of categories of cybersecurity problems including Web Exploitation, Reverse Engineering, Forensics, and Compromise (also known as Pwn). Mr Hopkins Kong, coach of the PolyU CTF Team and MPhil student in the EIE Department, has led the team “NuttyShell” to win the championship among a total of 6367 players worldwide.

Best Paper Award, the 22nd International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP’2022)

Dr Wenjuan Li and her research collaborators from the Aalborg University won the Best Paper Award in the 22nd International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP) 2022 for their paper "EnergyCIDN: Enhanced Energy-aware Challenge-based Collaborative Intrusion Detection in Internet of Things". ICA3PP is one of the most famous events of the world that covers the many dimensions of parallel algorithms and architectures, encompassing fundamental theoretical approaches, practical experimental projects, and commercial components and systems. Due to the structure, distributed intrusion detection may suffer from the insider threats, where a malicious node can share false information to influence the network performance. Dr Li's research team developed EnergyCIDN, an enhanced challenge-based collaborative intrusion detection network by adopting an energy-aware trust management model against advanced insider attacks. The proposed scheme can measure the reputation of an internal node by considering energy consumption, which is especially effective in an IoT environment. The results demonstrated that the proposed approach can be more robust against advanced insider attacks, compared with similar trust management schemes.
