Abstract (in Japanese) (See Japanese page) 
(in English) Since quantum computer is developed to be more practical, Post-Quantum Cryptography (PQC) that is not solved with quantum computer is more and more important. Lattice-based cryptography is very attractive as PQC. However, it has to sample random values from high-precise discrete gaussian and that is difficult phase of algorithm. In this paper, we propose hardware architecture of gaussian sampler that can generate arbitrary deviation gaussian samples by combining samples from fixed deviation gaussian sampler. Using this architectute, we show certain performance of lattice-based digital signature algorithm.
