Professor Johannes Buchmann

Professor Emeritus, Technical University of Darmstadt (TU Darmstadt), Germany

Professor Buchmann is a founder and pioneer in the field of global cybersecurity, particularly in cryptography and post-quantum cryptography (PQC). A leading figure in German science, he is a member of both the German Academy of Sciences (Leopoldina) and the German Academy of Engineering (acatech) . In 1993, he was awarded the Gottfried Wilhelm Leibniz Prize , Germany’s highest scientific honor, for his groundbreaking contributions to algorithmic number theory and cryptography.

Core achievements and influence:

• A visionary in the field of PQC: As early as 2003, Professor Buchmann foresaw the research of post-quantum cryptography and is one of the field’s global initiators.
• The XMSS hash signature scheme he developed was standardized in 2018, becoming the world’s first quantum-resistant international standard , demonstrating his profound theoretical foundation and practical expertise.
• Founder of a scientific research institution: He was the founding director of the renowned Center for Advanced Security Research in Darmstadt (CASED) , and he built the institution into a leading cybersecurity research center in Europe. He has made outstanding contributions to the development of the cybersecurity ecosystem in Germany and even the world.
• A prolific scholar, his book “Introduction to Cryptography” has become a standard textbook in universities worldwide. This seminar, based on his latest work, “Introduction to Quantum Algorithms,” published in 2024 , will provide participants with the opportunity to hear his authoritative interpretation of cutting-edge theories.

Professor Jintai Ding and his team

Professor Ding Jintai is a world-class leader in the field of post-quantum cryptography and a key standard designer . He has not only achieved remarkable theoretical research but also played a key role in the global PQC standardization process, with his work having a direct bearing on the development of the next-generation global information security infrastructure. Professor Ding holds a PhD in Mathematics from Yale University and is renowned for his earlier research in quantum affine algebra. Professor Ding is currently Dean of the School of Mathematical Physics and Director of the Post-Quantum Migration Interdisciplinary Laboratory at Xi’an Jiaotong-Liverpool University.

Core achievements and influence:

• Core Designer of the NIST PQC Standard: Professor Ding was one of the designers of the CRYSTALS-Kyber Key Encapsulation Mechanism (KEM) algorithm, which ultimately won the global PQC standardization competition held by the National Institute of Standards and Technology (NIST) and was selected as the official standard . This means that the core technology designed by Professor Ding will be widely used in the future global cybersecurity system.
• Inventor of the famous PQC algorithm: The ” Rainbow ” multivariate signature algorithm he designed , one of the world’s most famous PQC signature schemes, successfully entered the final round of the NIST PQC competition , fully demonstrating his top-notch capabilities in algorithm design.
• A renowned cryptanalysts, not only skilled at forging shields but also at breaking spears. They successfully cracked several candidate algorithms in the NIST PQC competition, such as LUOV and GeMSS, earning them a Best Paper honorable mention at CRYPTO 2021, a leading international cryptography conference , demonstrating their profound insight into PQC security.
