With the advancement of quantum computers, research on post-quantum cryptography has been progressing. The hash-based signature "SLH-DSA," standardized by NIST, offers high security but faces challenges due to the computational cost of signature generation. In this study, we designed low-latency signature generation hardware compatible with both SHA2 and SHAKE. This presentation focuses on the optimization of the SHA2 processor, where computational efficiency is particularly critical.
