Cryptanalysis of a Generalized Unbalanced Feistel Network Structure
Ruilin Li, Bing Sun, Chao Li, and Longjiang Qu
Abstract
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. For GF-NLFSR containing
