Dianzi Jishu Yingyong, 2021 NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.

Towards the Links of Cryptanalytic Methods on MPC/FHE/ZK-Friendly Symmetric-Key Primitives
IACR Transactions on Symmetric Cryptology, 2023 Symmetric-key primitives designed over the prime field Fp with odd characteristics, rather than the traditional Fn2 , are becoming the most popular choice for MPC/FHE/ZK-protocols for better efficiencies.

Integral Cryptanalysis on Reduced-Round KASUMI
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2018 Integral cryptanalysis, which was introduced by Knudsen and Wagner, is one of the most powerful attacks on symmetric key ciphers. Attackers preliminarily search integral characteristics of a target cipher for the key-recovery attack. Todo proposed a novel technique named the division property to find them efficiently.

Integral cryptanalysis of SAFER+
Electronics Letters, 1999 A new attack on block ciphers is introduced, which is termed integral cryptanalysis. It relies on similar principles to differential cryptanalysis, but is based on different statistics. It is shown that this method is more effective than differential cryptanalysis in attacking SAFER+.

Integral Cryptanalysis of the Block Cipher E2
CoRR, 2014 Block cipher E2, designed and submitted by Nippon Telegraph and Telephone Corporation, is a first-round Advanced Encryption Standard candidate. It employs a Feistel structure as global structure and two-layer substitution-permutation network structure in round function with initial transformation IT function before the first round and final ...
