Prof. Junji Shikata

Yokohama National University, Japan

Junji Shikata received the B.S. and M.S. degrees in mathematics from Kyoto University, Japan, in 1994 and 1997, respectively, and the Ph.D. degree in mathematics from Osaka University, Japan, in 2000. From 2000 to 2002, he was a Postdoctoral Fellow with the Institute of Industrial Science, The University of Tokyo, Japan. Since 2002, he has been with the Faculty of Environment and Information Sciences, Yokohama National University (YNU), Japan, and he is currently a Professor of YNU. In addition, he was the Dean of the faculty of YNU from 2021 to 2023, and he has been a Vice-President of YNU since 2023. From 2008 to 2009, he was also a Visiting Researcher with the Department of Computer Science, Swiss Federal Institute of Technology (ETH), Zurich, Switzerland. His research interests include cryptology, information theory, theoretical computer science, and computational number theory.

Achievements

Research Publications
He has published many papers on a wide range of research topics in cryptology. In particular, he has been engaged in research on developing cryptographic schemes secure against quantum computers as a next-generation cryptographic technology from multiple viewpoints, including post-quantum cryptography (PQC) from the viewpoint of computational security and information-theoretic cryptography from the viewpoint of unconditional security. Based on those achievements, he received many awards including the Wilkes Award from the British Computer Society in 2006. In addition, some cryptographic schemes he developed were internationally standardized in the ITU-T (International Telecommunication Union Telecommunication Standardization Sector).
Driving Research Projects
He has successfully completed many research projects. Currently, he is a principal investigator of a big research project "Research and development on new generation cryptography for secure wireless communication services" in Japan, which is supported by the Japanese government (i.e., the Ministry of Internal Affairs and Communications, Japan) from August 2022 to March 2025. The purpose of the research project is to develop quantum-resistant security technology based on PQC for B5G services, and thereby, to promote effective use of radio waves with appropriate security in the future.
Contributions to Society
From 2020 to 2024, he was a Program Officer of Informatics Group at the Research Center for Science Systems, Japan Society for the Promotion of Science (JSPS). He has also been a member of the CRYPTREC (Cryptography Research and Evaluation Committees) in Japan from 2019, and he was a WG Leader of Advanced Cryptography at CRYPTREC from 2021 to 2023. In addition, he is currently a Chair of Technical Committee on Information Security (ISEC) of the Institute of Electronics, Information and Communication Engineers (IEICE), Japan.
