This paper considers iterated ciphers and their resistance against linear and differential cryptanalysis. In the theory of these attacks one assumes independence of the round keys...
Algebraic attacks on stream ciphers [14] recover the key by solving an overdefined system of multivariate equations. Such attacks can break several interesting cases of LFSR-based ...
In this paper we present a variation of the template attack classification process that can be applied to block ciphers when the plaintext and ciphertext used are unknown. In a na...
In spite of growing importance of AES, the Data Encryption Standard is by no means obsolete. DES has never been broken from the practical point of view. The triple DES is believed ...
This paper is motivated by the design of AES. We consider a broader question of cryptanalysis of block ciphers having very good non-linearity and diffusion. Can we expect anyway, ...
