New Attacks on Feistel Structures with Improved Memory Complexities
Journal of CryptologyAbstract Feistel structures are an extensively researched type of cryptographic schemes. In this paper, we describe improved attacks on Feistel structures with more than 4 rounds. We achieve this by a new attack that combines the main benefits of meet-in-the-middle attacks (which can reduce the time complexity by ...

Provably Secure Encryption Algorithm based on Feistel Structure
International Journal of Computer Applications, 2016 The National Institute of Standards and Technology (NIST) started a process to select a symmetric-key encryption algorithm instead of DES. NIST determined the evaluation criteria that would be used to compare the candidate algorithms depending on the analyses and comments received, NIST selected five finalist algorithms (RC6, MARS, Rijndael, Serpent ...

On the Diffusion of Generalized Feistel Structures Regarding Differential and Linear Cryptanalysis [PDF]
, 2011 This paper studies the security of blockciphers with generalized Feistel structures (GFS) consisting of SP-type F-functions. While GFS leads to compact implementations, the security is not well understood, in particular for larger values of the partitioning number which indicates the number of subblocks.

Tweakable TWINE: Building a Tweakable Block Cipher on Generalized Feistel Structure
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2019 Tweakable block cipher (TBC) is an extension of conventional block cipher. We study how to build a TBC based on generalized Feistel structure (GFS), a classical block cipher construction. While known dedicated TBC proposals are based on substitution-permutation network (SPN), GFS has not been used for building TBC.
