On Fault Injections in Generalized Feistel Networks
, 2014 International audience—In this paper, we propose a generic method to assess the vulnerability to Differential Fault Analysis of generalized Feistel networks (GFN). This method is based on an in-depth analysis of the GFN properties. First the diffusion of

Type-2 Generalized Feistel Structures Based on Tweakable Block Ciphers, Reconsidered
IACR Communications in CryptologyGeneralized Feistel structures (GFSs) generalize a Feistel structure to have more flexible input length. Among them, Zheng et al. originally introduced type-2 GFS (CRYPTO '89) from pseudorandom functions (PRFs). This can be naturally instantiated with tweakable block ciphers (TBCs), which was analyzed by Nakaya and Iwata (ToSC 2022/

New Algorithm for Exhausting Optimal Permutations for Generalized Feistel Networks [PDF]
, 2023 The Feistel construction is one of the most studied ways of building block ciphers. Several generalizations were proposed in the literature, leading to the Generalized Feistel Network (GFN) construction, in which the round function operates on each pair ...

Constructing Zero-Sum Distinguishers of Two Generalized Feistel Structures
, 2015 由于Feistel结构具有良好的密码学性质, 它的变体许多广义Feistel结构也成为密码算法设计者乐于选择的对象, 其中由郑玉良等人设计的type-2和type-3广义Feistel结构被许多分组密码算法和密码杂凑函数所采用. 所以, 对这两种广义Feistel结构进行安全性分析非常必要. 伪随机性是一个结构的重要安全性指标, 而自2007年Knudsen和Rijmen提出了已知密钥区分器开始, 利用构造已知密钥区分器来分析算法与结构的伪随机性逐步成为人们常用的手段.
