Enhancing Differential-Linear Cryptanalysis [PDF]
, 2002 Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linear relations. In 1994, Langford and Hellman showed that both kinds of analysis can be combined together by a technique called differential-linear cryptanalysis, in which the ...

A New Guess-and-Determine Attack on the A5/1 Stream Cipher [PDF]
, 2012 In Europe and North America, the most widely used stream cipher to ensure privacy and confidentiality of conversations in GSM mobile phones is the A5/1. In this paper, we present a new attack on the A5/1 stream cipher with an average time complexity of 2^

XSL Block Ciphers’ Key-schedules with Resistance to Differential Cryptanalysis
Безопасность информационных технологий, 2014 The paper discusses the resistance of XSL block ciphers to differential cryptanalysis. AES-like block ciphers with alternative key-schedules (increased performance and density) are given as an example.

On a Linear Cryptanalysis of a Family of Modified DES Ciphers with Even Weight S-Boxes
Cybernetics and Information Technologies, 2016 We investigate the effect of inserting extra linearity in the Data Encryption Standard (DES) through appropriate nonsingular linear encodings of the output of the individual S-boxes.

Eliminating Variables in Boolean Equation Systems [PDF]
, 2017 Systems of Boolean equations of low degree arise in a natural way when analyzing block ciphers. The cipher's round functions relate the secret key to auxiliary variables that are introduced by each successive round.

Differential-Linear Cryptanalysis of Serpent [PDF]
, 2003 Serpent is a 128-bit SP-Network block cipher consisting of 32 rounds with variable key length (up to 256 bits long). It was selected as one of the 5 AES finalists. The best known attack so far is a linear attack on an 11-round reduced variant.

Linear cryptanalysis of stream ciphers [PDF]
, 1995 Starting from recent results on a linear statistical weakness of keystream generators and on linear correlation properties of combiners with memory, linear cryptanalysis of stream ciphers based on the linear sequential circuit approximation of finite-state machines is introduced as a general method for assessing the strength of stream ciphers.

A note on some algebraic trapdoors for block ciphers
, 2018 We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al.
