A new quantum cryptanalysis method on block cipher Camellia
IET Information Security, 2021 Symmetric cryptography is expected to be quantum safe when long‐term security is needed. Kuwakado and Morii gave a 3‐round quantum distinguisher of the Feistel cipher based on Simon's algorithm.

Tweaking Key-Alternating Feistel Block Ciphers [PDF]
, 2020 Tweakable block cipher as a cryptographic primitive has found wide applications in disk encryption, authenticated encryption mode and message authentication code, etc. One popular approach of designing tweakable block ciphers is to tweak the generic constructions of classic block ciphers.

Practically secure Feistel ciphers [PDF]
DAIMI Report Series, 1994 In this paper we give necessary design principles to be used, when constructing secure Feistel ciphers. We introducee a new concept, <strong> practical security</strong> against linear and differential attacks on Feistel ciphers. We give examples of such Feistel ciphers (practically) resistant to differential attacks, linear attacks and ...

Integral Cryptanalysis of WARP based on Monomial Prediction
IACR Transactions on Symmetric Cryptology, 2022 WARP is a 128-bit block cipher published by Banik et al. at SAC 2020 as a lightweight alternative to AES. It is based on a generalized Feistel network and achieves the smallest area footprint among 128-bit block ciphers in many settings.
