Towards reliable and secure network systems

The professors of the laboratory belong to the Cyberscience Center which carries out management and promotion of information infrastructure of Tohoku University, and the followings are related research fields.

(1)  Basic and application research on flexible information networks

Our goal is to realize information networks that support the next-generation information society where people, the environment, and IT coexist. With flexible network construction and management technologies at the core, we are promoting R&D on SDN, sensor networks, IoT, network middleware, authentication infrastructure, and various application systems.

(2)  Theoretical foundations of information security

We study fundamentals of cryptography, which are increasingly important. Specifically, we are carrying out research on constructing information-theoretically secure cryptosystems such as protocols for secure computations using a deck of cards and methods for sharing secret keys from partially leaked pre-shared information.

(3)  Operation/management plan and application services of information networks

Research and development on these topics are included in the activity of the Center.
