- Cryptography
- Modern cryptography has become one of the most important research fields in information technology. We aim at development and security evaluation of the next-generation cryptographic systems. In particular, we study post-quantum
cryptography based on the mathematical problems (such as coding theory, lattice theory, multivariate polynomials,
graph theory, etc), which are computationally intractable even in the era of quantum computing.
- Information Security
- With cryptography it is possible to construct many security protocols that become the basic infrastructure for secure
communications such as SSL/TLS. These security protocols provide us with various security applications, for example,
copyright protection, electronic voting, cryptocurrency, and so on. This research group is engaged in the development
of new efficient cryptographic algorithms and implementation secure against physical attacks.
