Prof. LUO Xiapu’s Team Wins Prestigious Best Practical Paper Award at Cybersecurity Award 2025 by SpringerOpen

A team consisting of our academic staff and PhD students has been selected as the winner of the “Best Practical Paper” in the Cybersecurity Award 2025. This annual award, presented by the journal Cybersecurity (SpringerOpen), recognises research papers that demonstrate outstanding and groundbreaking contributions to the field of cybersecurity.   The winning paper, titled "DoubleUp Roll: Double-spending in Arbitrum by Rolling It Back," was presented at the 2024 ACM SIGSAC Conference on Computer and Communications Security (CCS '24). The authors of the paper include: Mr Zhiyuan SUN (COMP PhD Student) Dr Zihao LI (COMP Postdoctoral Fellow) Mr Xinghao PENG (COMP PhD Student) Prof. Xiapu LUO (Associate Dean (Research), Faculty of Computer and Mathematical Sciences; COMP Professor) Dr Muhui JIANG (COMP PhD Graduate) Dr Hao ZHOU (COMP Research Assistant Professor) Prof. Yinqian ZHANG (Southern University of Science and Technology)   This research paper identifies critical vulnerabilities in widely-used optimistic rollup protocols, specifically Arbitrum and Optimism. It reveals three novel double-spending attacks, including overtime attack, queuecut attack, and zip-bomb attack, which could allow attackers to steal funds from cross-chain applications at no cost. These severe vulnerabilities were promptly reported to the Arbitrum and Optimism teams, who recognised the contributions with significant bug bounties and resolved the issues. This research prevented potential damages that could have escalated to billions.   Congratulations to our outstanding team for their remarkable achievement and for making a significant impact on the security of blockchain technologies!   For more information about the award, please click here.

Prof. Yang Hongxia Secures Theme-based RGC Funding for Groundbreaking Collaborative Generative AI Project

Prof. YANG Hongxia, Executive Director of the PolyU Academy for Artificial Intelligence, Associate Dean (Global Engagement) of the Faculty of Computer and Mathematical Sciences and our Professor, has received a total of HK62.6 million funding from the Research Grants Council’s (RGC) Theme-based Research Scheme 2025/26 for her pioneering project, “Collaborative Generative AI (Co-GenAI).”   The project has been awarded a total of HK62.6 million in funding, with HK41.79 million provided by the RGC and the remaining matched by PolyU and other participating universities. This initiative is aimed at reshaping the landscape of GenAI in a decentralised way. The research holds significant potential to strengthen Hong Kong’s position as a global leader in GenAI development, with real-world applications in healthcare and technology.   Led by Prof. YANG, the Co-GenAI project seeks to establish a novel collaborative paradigm in Generative AI. By integrating several hundred domain-specific models, the team aims to develop a foundation model capable of achieving artificial general intelligence (AGI) with significantly reduced reliance on centralised computational resources. This innovative approach addresses the current limitations posed by GPU monopolies, paving the way for more inclusive and accessible AI development.   Co-GenAI is designed to foster cross-domain collaboration and enhance the versatility of GenAI platforms. Key objectives include building a domain-adaptive continual pre-training infrastructure, developing a robust and generalisable model ranking methodology, and implementing an advanced model with a fusion approach to merge heterogeneous top-ranked domain-specific models.   To evaluate the Co-GenAI, the research team will collaborate with industry partners such as Cyberport, Hong Kong Science and Technology Park, Alibaba, and leading hospitals, including Huashan Hospital affiliated to Fudan University, Shandong Cancer Hospital, and Sun Yat-sen University Cancer Center, by deploying the technology across a wide range of practical applications.   The RGC’s Theme-based Research Scheme aims to pool the research strengths of UGC-funded universities to address topics of strategic importance for Hong Kong’s long-term development. Projects are evaluated based on their potential to achieve world-leading standards and impact on Hong Kong.
