Accurate Estimation of the Full Differential Distribution for General Feistel Structures
2016Statistical cryptanalysis is one of the most powerful tools to analyze symmetric key cryptographic primitives such as block ciphers. One of these attacks, the differential attack has been demonstrated to break a wide range of block ciphers. Block cipher proposals previously obtain a rough estimate of their security margin against differential attacks ...

Cryptographic Properties and Application of a Generalized Unbalanced Feistel Network Structure (Revised Version). [PDF]
IACR Cryptol. ePrint Arch., 2009 In this paper, we study GF-NLFSR, a Generalized Unbalanced Feis- tel Network (GUFN) which can be considered as an extension of the outer function FO of the KASUMI block cipher. We show that the differential and linear probabilities of any n + 1 rounds of

GFLE: a low-energy lightweight block cipher based on a variant of generalized Feistel structure
Physica ScriptaAbstract Low-energy lightweight block ciphers are essential for applications with extremely resource-constrained to reduce energy and maintain security. The trade-off between diffusion property and area is a widely studied issue in the design of low-energy block ciphers.
