What is K Pro High-Performance Encryption PQC?

The objective of this research project is to develop advanced cryptographic schemes that remain secure even against various threats such as attacks by quantum computers and side-channel attacks. Advanced cryptography enables the realization of various cryptographic protocols with wide-ranging applications, including fully homomorphic encryption, functional encryption, blind signatures, ring signatures, and secure computation. We promote research and development on the mathematical structures of underlying computational problems and on efficient implementation algorithms for advanced cryptographic schemes based on post-quantum cryptographic primitives, such as lattice-based cryptography, code-based cryptography, multivariate polynomial cryptography, and isogeny-based cryptography.

This research project is supported by JST K Program Grant Number JPMJKP24U2, Japan.
