Introduction to laboratory

Now is the age of information and communication society. There are many wireless communication devices around us. Interface of the wireless communication equipment and space is the antenna. Around the antenna technology, our laboratory has been studying the art of wireless communication networks and Ranging. Recently, we have also studied OFDM acoustic modem and detection of discontinuity of the pipe using sound waves.

Yoshimichi ITO

Research in our laboratory;

In order to control a given system freely or, in other words, in order to make a given system behave in a desirable manner, it is very important to know the nature of the system and to describe the nature in an appropriate fashion. Mathematics plays a key role for this purpose, that is, we replace the engineering problem of controlling a given system, with an appropriately described mathematical problem. The theory dealing with such problems is called control theory, and is applied to various fields. In our laboratory, we apply the theory and mathematics to some problems of control system design, media processing, and computer vision, and develop new systems that are interesting and useful in the world.

Associate Professor
Ryuichi SAKAI
[Information Security Laboratory]

Research Fields;

Cryptography, Information Security, biometric authentication

Biography;

I received the B.S., M.S, and Ph.D. degrees from Kyoto Institute of Technology, Kyoto, Japan.
I have widely studied cryptography and information security from the theory to the application.
One of the aims of the study is to build new cryptographic schemes for improving safety and convenience.

Ryuichi SAKAI

Research in our laboratory;

Cryptography and information security are fundamental technology to realize secure information network and secure system.

Schemes of public key encryption, identity based encryption, broadcast encryption and attribute based encryption are improved user's safety and convenience.

These schemes are actively studied and hot topics in cryptographers.

In this laboratory, we study theory and application of these schemes.

Biometric authentication schemes are also enhanced user's convenience and we also study face authentication with video date.

Yasuyuki MURAKAMI

Research in our laboratory;

The security of most of the public-key cryptosystems depends on the difficulty of the factoring problem, the discrete logarithm problem or the elliptic curve discrete logarithm problem.

It is shown that the quantum computer can solve these problems in polynomial time.

In our laboratory, we have been studying and proposing new public-key cryptosystems.

Our goal is to construct the cryptosystems which are secure against the quantum computer.
