Computer-Aided Proof for Extended Generalized Feistel Networks
(Multi-branch) Generalized Feistel Network (GFN) enables the construction of block ciphers from non-linear components with small domains, and has been adopted in various block ciphers. Berger et al. (SAC 2013) introduced the Extended Generalized Feistel

Deck-Based Wide Block Cipher Modes and an Exposition of the Blinded Keyed Hashing Model
We present two tweakable wide block cipher modes from doubly-extendable cryptographic keyed (deck) functions and a keyed hash function: double-decker and docked-double-decker.

Refined Probability of Differential Characteristics Including Dependency Between Multiple Rounds
The current paper studies the probability of differential characteristics for an unkeyed (or with a fixed key) construction. Most notably, it focuses on the gap between two probabilities of differential characteristics: probability with independent S-box

Cryptanalysis of a Generalized Unbalanced Feistel Network Structure [PDF]
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.

Decorrelation: A Theory for Block Cipher Security [PDF]
Pseudorandomness is a classical model for the security of block ciphers. In this paper we propose convenient tools in order to study it in connection with the Shannon Theory, the Carter-Wegman universal hash functions paradigm, and the Luby-Rackoff ...

Quasigroups generated by shift registers and Feistel networks
Formula-based specification of large quasigroups with the use of complete mappings over Abelian groups is investigated. Complete mappings specified by generalized feedback registers and generalized Feistel networks are considered. In both cases criteria for the mapping completeness are established.

THE AVALANCHE EFFECT IN ENCRYPTION ALGORITHMS BASED ON THE DISCRETE CHAOTIC MAPS
The avalance effect has been investigated in an encryption algorithm being developed on the basis of the discrete chaotic maps. The avalanche effect has been analyzed in a discrete tent map and in the basic transformation based on the Feistel network ...
