Cryptanalysis of a Generalized Unbalanced Feistel Network Structure [PDF]

Australasian Conference on Information Security and Privacy, 2010
This paper reevaluates the security of GF-NLFSR, a new kind of generalized unbalanced Feistel network structure that was proposed at ACISP 2009. We show that GF-NLFSR itself reveals a very slow diffusion rate, which could lead to several distinguishing attacks.

Quantum Round Key Recovery Attack on Extended Generalized Feistel Network

2024 IEEE 5th International Conference on Advanced Trends in Information Theory (ATIT)
In this paper, we analyse the extended generalized Feistel-like scheme and construct new quantum distinguishing attacks as well as multiple new quantum round key recovery attacks on this scheme with polynomial complexity. The obtained result implies that

Indifferentiability of 8-Round Feistel Networks

2016
We prove that a balanced 8-round Feistel network is indifferentiable from a random permutation, improving on previous 10-round results by Dachman-Soled et al. and Dai et al. Our simulator achieves security $$Oq^8/2^n$$, similarly to the security of Dai et al. For further comparison, Dachman-Soled et al.
