Evolution of Cryptography
In this research project, in order to avoid the compromise of cryptography, we consider various possible attackers such as attacks using quantum computers and side-channel attacks by power analysis. We will promote research on mathematical foundations aimed at the realization of cryptographic technology that is resistant to such attacks.
Furthermore, we will build a cryptographic system with a decentralized security function using blockchain for large-scale distributed systems.
