On Multiple Linear Approximations
In this paper we study the long standing problem of information extraction from multiple linear approximations. We develop a formal statistical framework for block cipher attacks b...

Feistel Schemes and Bi-linear Cryptanalysis
Abstract. In this paper we introduce the method of bi-linear cryptanalysis (BLC), designed specifically to attack Feistel ciphers. It allows to construct periodic biased character...

Improved Attacks on Full GOST
GOST is a well known block cipher which was developed in the Soviet Union during the 1970’s as an alternative to the US-developed DES. In spite of considerable cryptanalytic eff...

Structural Cryptanalysis of SASAS
In this paper we consider the security of block ciphers which contain alternate layers of invertible S-boxes and affine mappings (there are many popular cryptosystems which use thi...

SGCM: The Sophie Germain Counter Mode
Abstract. Sophie Germain Counter Mode (SGCM) is an authenticated encryption mode of operation, to be used with 128-bit block ciphers such as AES. SGCM is a variant of the NIST stan...
