Quantum Distinguishing Attacks against Type-1 Generalized Feistel Ciphers [PDF]
, 2019 A generalized Feistel cipher is one of the methods to construct block ciphers, and it has several variants. Dong, Li, and Wang showed quantum distinguishing attacks against the $(2d-1)$-round Type-1 generalized Feistel cipher with quantum chosen ...

Generic Key Recovery Attack on Feistel Scheme [PDF]
, 2015 We propose new generic key recovery attacks on Feistel-type block ciphers. The proposed attack is based on the all subkeys recovery approach presented in SAC 2012, which determines all subkeys instead of the master key. This enables us to construct a key

Avalanche Analysis of Extended Feistel Network [PDF]
, 2005 In general, block ciphers consist of one top-level structural model into which the round function F is plugged into. In order to analyze the security of a cipher, it is also important to study the intrinsic security provided by these top-level ...

Integral attack on MIBS block cipher
Tongxin xuebao, 2014 The security of the block cipher MIBS against integral attack was analyzed and a 5-round distinguisher of MIBS was founded. Considering the equivalent structure of Feistel structure and the relation of master key and round key in the key expansion ...

FeW: A Lightweight Block Cipher [PDF]
, 2014 : In this paper, we propose a new lightweight block cipher called FeW 1 which encrypts 64-bit plaintext using key size 80/128 bits and produces 64-bit ciphertext.

Lai-Massey Scheme and Quasi-Feistel Networks (Extended Abstract) [PDF]
, 2008 . We introduce the notion of quasi-Feistel network, which is generalization of the Feistel network, and contains the Lai-Massey scheme as an instance.

Generalized Feistel Ciphers for Efficient Prime Field Masking
A recent work from Eurocrypt 2023 suggests that prime-field masking has excellent potential to improve the efficiency vs. security tradeoff of masked implementations against side-channel attacks, espe- cially in contexts where physical leakages show low noise. We pick up on the main open challenge that this seed result leads to, namely the design of an
