Rigorous upper bounds on data complexities of block cipher cryptanalysis
Journal of Mathematical Cryptology, 2017 Statistical analysis of symmetric key attacks aims to obtain an expression for the data complexity which is the number of plaintext-ciphertext pairs needed to achieve the parameters of the attack. Existing statistical analyses invariably use some kind of

Improved Linear Cryptanalysis of Reduced-round SIMON [PDF]
, 2014 SIMON is a family of ten lightweight block ciphers published by Beaulieu et al.\ from U.S. National Security Agency (NSA). In this paper we investigate the security of SIMON against different variants of linear cryptanalysis techniques, i.e.\ classical ...

From Differential Cryptanalysis to Ciphertext-Only Attacks [PDF]
, 1998 . We present a method for efficient conversion of differential (chosen plaintext) attacks into the more practical known plaintext and ciphertext-only attacks. Our observation may save up to a factor of 2 20 in data over the known methods, assuming that

Multidimensional linear cryptanalysis [PDF]
, 2010 Linear cryptanalysis is an important tool for studying the security of symmetric ciphers. In 1993 Matsui proposed two algorithms, called Algorithm 1 and Algorithm 2, for recovering information about the secret key of a block cipher.

Linear Cryptanalysis of Round Reduced SIMON [PDF]
, 2014 SIMON is a family of lightweight block ciphers that was proposed by U.S National Security Agency (NSA). A cipher in this family with $K$-bit key and $N$-bit block is called SIMON ${N}/{K}$.

Advanced methods of Linear Cryptanalysis [PDF]
, 2011 In the present work we study advanced methods of linear cryptanalysis. At the beginning, we describe the principle of Matsui's linear cryptanalysis, the two basic algorithms - Algorithm 1 and Algorithm 2, against DES cipher.
