Abstract (in Japanese) (See Japanese page) 
(in English) In CSS2021, Nakahashi et al. showed an optimal Feistel-type large-state permutations using only AES-NI from the security evaluation against differential/linear attacks. In this study, we further evaluate the security of the constructions targeted by Nakahashi et al. against the impossible differential/integral attacks and search for optimal constructions. We also implemented the optimal constructions as a hash function and compared the speed with existing constructions. As a result, we show that the encryption with 256-bit and 512-bit permutations and hash functions we identified are faster than that with the existing constructions.
