To deal with message streams, which is required by many symmetric cryptographic functionalities (MAC, AE, HASH), we propose a lightweight round function called Thin Sponge. We give a framework to cons...
Generic Round-Function Recovery for Feistel Networks over Small Domains
feistel networks format-preserving encryption
2018/1/31
Feistel Networks (FN) are now massively being used to encrypt credit card numbers through format-preserving encryption. In our work, we focus on FN with two branches, entirely unknown round functions,...
Efficient Design Strategies Based on the AES Round Function
Fast Software Implementation AES AES-NI
2016/3/18
We show several constructions based on the AES round function
that can be used as building blocks for MACs and authenticated
encryption schemes. They are found by a search of the space of all secure...
Simpira: A Family of Efficient Permutations Using the AES Round Function
cryptographic permutation AES-NI Generalized Feistel Structure (GFS)
2016/2/23
This paper introduces Simpira, a family of cryptographic
permutations that supports inputs of 128 × b bits, where b is a positive
integer. Its design goal is to achieve high throughput on virtually

Cryptanalysis of Symmetric Block Ciphers Based on the Feistel Network with Non-bijective S-boxes in the Round Function
block ciphers Feistel network ciphertext-only attack
2012/6/14
We consider ciphertext-only attack on symmetric block ciphers based on the Feistel network with secret S-boxes installed as an additional parameter, like in Soviet GOST 28147-89. In case when S-boxes ...

From Camellia to p-Camellia: Some Observations on MISTY Structure with SPN Round Function
Block ciphers Camellia p-Camellia Feistel MISTY SPN Structural properties
2011/1/5
At AFRICACRYPT 2010, a parallelized version of the block cipher Camellia, called p-Camellia, was proposed. The high level structure of p-Camellia is MISTY-type, while the round function is SPN-type. I...

Security on Generalized Feistel Scheme with SP Round Function
Differential cryptanalysis Linear cryptanalysis Branch number
2009/4/2
cryptanalysis and the pseudorandomness for a class of generalized Feis-
tel scheme with SP round function called GFSP. We consider the mini-
mum number of active s-boxes in some consecutive rounds o...
In the paper we present the results which enable to calculate the
nonlinearity of round functions with quite large dimensions e.g.
32 × 32 bits, which are used in some block ciphers. This can be
