Dr. Takanori Isobe received his B.E. degree in electrical and electronic engineering and master’s and Ph.D. degrees in engineering from Kobe University in 2006, 2008, and 2013, respectively. He was a researcher at Sony Corporation from 2008 to 2017. From 2017, he was an Associate Professor at the Graduate School of Information Science, University of Hyogo, Japan, and was subsequently to promoted Professor of that university in 2023.

Dr. Takanori Isobe has pioneered the development of new-generation cryptography for extremely demanding environments such as IoT and Beyond 5G networks. His related papers have been published in over 40 top conferences and journals in the field of cryptography, and have been cited over 2,000 times, making significant academic contributions and leading the field globally.

He has developed lightweight cryptographic algorithms for IoT devices, including the low-circuit-size ciphers Piccolo and WARP, and low-energy cipher Midori. Piccolo and WARP reduces circuit size to approximately 600 GE, which is about 1/5 of the standard AES, by optimizing nonlinear functions required for cryptographic operations at the logic gate level. As of 2023, this is the world's smallest in circuit size. Furthermore, Midori successfully minimized energy consumption to 1/10 of that of AES by constructing a theoretical model that takes into account leakage current. As of 2023, it also has the world's best low-energy performance.

For Beyond 5G networks, he has developed the ultra-fast cryptographic algorithm Rocca and the low-latency cipher Orthros. Rocca adopts an approach that constructs a cryptographic algorithm from only instructions that can be executed quickly in software, achieving significant software acceleration. As a result, it has achieved software throughput of over 100 Gbps and quantum-computer security for the first time, which are the requirements of Beyond 5G . Its software encryption speed is more than five times faster than that of AES, making it the world's fastest cryptographic algorithm today. Orthros minimizes computational delay by optimally combining components with small delays required for operations. As a result, it achieves low-latency encryption at a sub-nanosecond level, which is a requirement for real-time encryption in the Beyond 5G era, with more than 1/3 lower latency performance than AES, and is the world's first to achieve this.

As described above, Dr. Isobe has made remarkable contributions in the fields of electronics, information, and communication and is deserving of this award. We look forward to further progress in his research and his future activity.
