Research

For the last decade or so, I have been researching high-performance cryptography, anonymous digital signatures and privacy-preserving authentication for the Internet. One type is called 'attribute-based'. The design idea is to open up the possibility of exchanging information based on various attributes of our users, but without telling them who they are (anonymous). The design approach uses information mathematics. In particular, in the last two years, we have been seeking to strike a balance between allowing a 'tracking key' to be used by the administrator in an emergency to reveal anonymity and identify the user, while allowing the user to actively control the use of the tracking key in part.

Message to candidates and students

The mathematical part of information mathematics is considered to be a practical skill up to a certain level. When you hear the word practical skills, what surely comes to mind is PE. 'Yay, I don't have to study! I don't have to study. I'm going to move my body! You don't have to study mathematics either, which is a practical skill in your head. Instead, you move your head. During the first two years of school, you will move your head a lot, learn to be careful and have a sense of balance, and build up your muscular strength and endurance. What I'm talking about is the thrilling tightrope walk in the invisible mathematical world. Then, around the third year, you enter the magical world of information mathematics, exploring and challenging yourself to find out how to hang on to the rope. I myself am now doing academic work in the area of cryptography theory. Would you like to get excited (and thrilled) together? In doing so, please bring one thing with you. Please bring with you the feeling of wonder that you have inside of you. We are waiting for you, hoping that it is related to information mathematics.
