The 21st International Conference on Information Security and Cryptography was recently held in Xi'an. Zhou Wanlei, Vice Rector of City University of Macau, was invited to attend and delivered a keynote speech titled "Research on Key Technologies of Large Language Models Driven by Ethics and Security".

This conference was co-hosted by the State Key Laboratory of Integrated Services Networks (ISN) at Xidian University and the Key Laboratory of Network and Information Security of the Chinese Academy of Sciences (CAS Institute of Information Engineering). It brought together experts and scholars from a number of universities and research institutions around the world, including Columbia University (USA), Lancaster University (UK), University of Wollongong (Australia), Singapore Management University (Singapore), University of Aizu (Japan), Tsinghua University, National University of Defense Technology, Renmin University of China, CAS Institute of Information Engineering, Xidian University, Jinan University, and Wuhan University.

In his speech, Vice President Zhou Wanlei pointed out that as a major technological breakthrough in the field, artificial intelligence large language models have become a core driving force for promoting the transformation of the technology industry and innovation in the technology ecosystem. However, if the development and application of large language models fail to take both security and ethics into account, deficiencies in either aspect will severely restrict their practical application and even lead to consequences that violate laws and regulations. Although building secure, trustworthy, and ethical large language models has become a common goal of the academic and industrial communities, current large language models still face significant challenges in achieving this goal. He further stated that the research team of City University of Macau has conducted systematic exploration on the evaluation mechanism of large language models from the dual perspectives of ethical constraints and security requirements, as well as the balance between optimization and security proof. The team has focused on making breakthroughs in key issues such as the quantitative evaluation of ethics and security, ethics-security balance technology based on game theory, and relevant provable security theories and demonstration methods.

This conference called for high-quality academic papers globally, covering a number of cutting-edge research topics in the fields of information security, cryptography, and their applications. The accepted papers after review will be officially published by Springer and included in the Lecture Notes in Computer Science (LNCS) series.
