TAKAGI GROUP
Project Title
Creation and development of mathematical foundations for cryptography required by the post-quantum society
Outline of Research
We will study the security and efficiency of multivariate polynomial cryptography, lattice-based cryptography, and isogeny-based cryptography, which are the main candidates for post-quantum cryptography. In particular, we will study the difficulty of the shortest vector problem (SVP), the multivariate polynomial solution (MQ) problem, and the isogeny problem, which are the basic mathematical problems that support the security of these cryptosystems. We will also consider reducing the relatively large public key size of post-quantum cryptography and speeding up the processing of cryptographic operations.
